General Bug Website Links
Mark Cassino's "Page 2000" website This private individual's website is packed with very high quality and very artistically photographed insects and spiders, as well as other subjects of general interest.
Insects on the World Wide Web This is a list maintained by the entomology department of the University of Vermont in the USA.
Insect and Spider Collections of the World This database of insect and spider collections around the world includes a search engine, but it only allows you to find the collection, not to find which collections have a particular species.
Smithsonian National Museum of Natural History Entomology Dept The Smithsonian Institute maintains this entomology website which includes a database library, which contains information about the specimens in the Smithsonian Institute collection, but no photos or species data.

Bug Website Links by Region
Asia  
India Nature Watch The best, and a little bit of the worst, of the internet.   The galleries (such as the butterfly and moth gallery) consist of photos posted by members of the public.   Surprisingly, they're of generally good quality but unfortunately they're totally unsorted, and there are even photos of dragonflies, crickets and birds in the lepidoptera gallery.   With 40 large thumbnails per page, you'll eventually find what you're looking for, but with 3790 photos in this one gallery, it might a while!   The galleries also function as forums, so this is a very good place to ask people for an ID of what you've photographed.   Last visited in December of 2008.

Australia  
CSIRO Entomology The Commonwealth Scientific and Industrial Research Organization was Australia's premier government funded research establishment, but is now increasingly trying to pay its own way by charging people to use its facilities and expertise.   There are some insect identification pages with photos categorized by insect or spider type, but there's so little information here that you might as well not bother - the "butterfly and moth" page, for instance, had exactly one photo when I visited in October of 2003.  The website is only salvaged by its large list of images listed by name - but each insect has its own separate page, making identification of an unidentified insect a nightmare.
   
Costa Rica  
INBIOS The Instituto Nacional de Biodiversidad is a Costa Rican scientific research organization.   The website is primarily in Spanish, but with an English introductory section.   There's a section called UBIs which has photo galleries of various categories of animal and plant life; it's in Spanish, but I found it useful because it has photos and latin names for everything.

Insects and Spiders of New Zealand This government sponsored website is very short on information, and the website links page has very few links to New Zealand insect and spider websites.

Thailand  
TWITstreams World Sub-titled "More idiots every day", few people would guess that this is actually the website of a butterfly and moth afficianado living on the island of Phuket.   His regular blog describes the critters he collects and breeds, with good photographs and enlightening text.   Last visited in April of 2009.
ThaiBugs.com John Moore is an amateur entymologist living near Chiang Mai in Thailand.   He has amassed a huge collection of arthropod photos from this area, split into photo galleries arranged by the type of "bug", as well as some galleries of amphibians and snakes.   It's an excellent resource, however quite a few of the photo links are broken, the photos are not always very large or clear, and the species is often not identified.   Last visited in April of 2009.
USA  
What's That Bug? This website provides identification pages for many different types of arthropod.   Each type of insect, spider or other arthropod has one or more pages with photos sent in by people trying to identify some bug they've found.  The photo quality is therefore not always brilliant, the photos are a little small and each of the pages is huge, but this is still a useful resource, though it might take a while to track down what you've seen.  A more compact photo gallery would certainly have made life easier.   Last visited in January of 2007.
Elytra and Antenna OK, maybe they should have called it "Elytra and Antennae", but nevertheless this website is good, with a photo gallery of America's most interesting beetles, walking sticks, bugs, grasshoppers, crickets, katydids and giant moths.  Each photo is accompanied by a description geared towards raising the insect in captivity.  There's a separate photo gallery of centipedes, millipedes and spiders.
Field Guide to Common Texas Insects This website by the Texas A&M University Entomology Department has photo galleries with links to species from many different insect and non-insect animal orders.   Each link takes you to a page with a photograph and description of the species.   Unfortunately the photos in the photo galleries are of poor quality.

Ants
Lurker's Guide to Leafcutter Ants Alan San Juan has put together a very good website devoted to leafcutter ants, with information about their behavior and a good photo gallery.


Beetles
Eudicella.com This website is entirely devoted to stag beetles, rhinoceros beetles and other members of the scarab family.   Anyone who thinks that beetles are ugly should be pointed straight to the Eudicella website's flower beetle photo gallery, which contains about 50 photographs of exquisitely beautiful beetles.   Last visited in August of 2007.


Butterflies

General Butterfly Information
 
The Butterfly Website This website is fairly well presented, with photo galleries for butterflies, moths and caterpillars.   These photo galleries are accessed by the name of the thing you're looking for, which is good if you already know the name but not so good if you have a picture of a butterfly you want to identify.   The website also has a large list of other butterfly and moth websites.
WildlifeWebSite.com - butterflies and moths This website is polluted with advertising and the photo galleries aren't too great, but it has a good "butterflies and moths of the world" section consisting of links to butterfly and moth websites, sorted by geographical area.
The Butterfly Site The "butterfly pictures" link on this commercially oriented website takes you to an annotated list of about 30 websites with butterfly photos.
Electronic Resources on Lepidoptera The information on this website isn't very accessible (for instance, the lepidoptera image archive is fragmentary and doesn't have proper thumbnails), but there are excellent lists of links to other websites, including lists of websites with photo identifications
The Lepidopterists' Society This scientifically oriented website is currently sitting on a university web server, which means it might move somewhere else in the future.   Like the Association for Tropical Lepidoptera the idea of putting photos of butterflies and moths onto the website seems to be beyond them, but they have a huge list of scantily annotated links to other butterfly and moth websites.   Last visited in June of 2006.
Enchanted Learning butterfly glossary The Enchanted Learning website is aimed at children and has a huge glossary of butterfly terminology, with a page devoted to each letter of the alphabet.   Last visited in March of 2008.
Butterflies of the Carolinas and Virginias I've encountered Randy L. Emmett's website several times when hunting for information on various topics.   This information and photographs are always very good; the main butterfly page doesn't look too promising, but as soon as you select one of the galleries things get much better.   Last visited in March of 2009.
A World For Butterflies Phil Schappert is the author of a very good book called A World For Butterflies.   His website has information about the book, a small website links page and a list of the websites of some butterfly photographers whose work is in the book.
James Mallet's Lepidoptera Website This researcher's website contains a useful page of links to websites describing tropical butterflies and moths, and where to find information on heliconius butterflies.   The information is excellent, but it's very academically oriented and very limited in scope.   Last visited in December of 2005.
Association for Tropical Lepidoptera This could be an extremely good website, but unfortunately it's almost totally worthless.   The Association publishes two scientific journals but they haven't woken up to the possibilities of the internet.   I couldn't find any photographs on the website, the link to the "index to species images" is broken and the photo registry is an inaccessible database of slides which people are invited to contribute to.   Try back later, perhaps they'll get their act together.

Butterfly Information by Country
Costa Rica  
Butterflies of Monte Verde This website does a good job of documenting the butterflies of Monte Verde in Costa Rica.   There's a useful list of Costa Rican lepidopteran websites and a special section on Monte Verde's clearwing butterflies.
The Butterfly Farm This website belongs to The Butterfly Farm, which is located near San Jose in Costa Rica.   They've improved their photo gallery since I first visited, though the quality of the photos still isn't great.
   
Japan  
Butterflies of Japan This website starts off with some annoying music which will probably drive you to silence your computer's speakers, but the galleries of Japanese butterflies, including their caterpillars and even some eggs, make up for this irritation!  There's an all-in-one gallery with most of the site's butterflies, which makes butterfly identification much faster.   Unfortunately the website hasn't been updated in the last two years.   Last visited in June of 2006.
Japanese Butterfly Gallery There are some good photos on this website, unfortunately they can only be indexed by name.   If you don't know the name, then you have to scroll through page after page, with only one species on each page.
   
Malaysia  
Chin's Butterfly Gallery Chin Fah Shin is a butterfly enthusiast who lives in Kuala Lumpur in Malaysia whose website consists of photo galleries divided into families.   The larger photos aren't perfect but are more than adequate for identification purposes and he provides the scientific and common names for each butterfly.   The website is full of commercials, both embedded and occasional popups and there's also a little religious proselytization.   Last visited in December of 2008.
   
Mexico  
Neotropical Butterflies This is a very valuable resource for identifying Mexican butterflies, with an excellent set of butterfly photo galleries arranged by family.   It misses out on five stars only because the photos often don't show the butterfly both with wings open and wings closed, and because the species pages contain photographs but next to no information about the species.   Last visited in March of 2008.
Mariposas Mexicanas The website name might be in Spanish, but this "Interactive Listing of Mexican Butterflies" also gives you the choice of navigating in English.   The website is a bit crude and text heavy, and unfortunately it's one of those websites which is only much good if you already known the species, or at least the genus, of the butterfly you're interested in.   Last visited in March of 2008.
   
Singapore  
Butterfly Circle This is a more professional follow-on to the same individual's "Butterflies of Singapore", which is now obsolete.   The earlier website received four stars because of good content, and the new website has kept all of this content including the photo galleries, laid it out better and incorporated a very nice looking graphic design, though it might be nice if the slightly inconspicuous "photo checklist" entry in the navigation menu was changed to "photo gallery".   There's also a very active blog associated with the site.   Last visited in August of 2009.
   
Thailand  
TWITstreams World Go to my review of this website.
   
USA  
Butterflies and Moths This website is based on a now defunct website operated by the United States Geological Survey.   There are good photo galleries listed by family, which include some caterpillar photos, but the galleries suffer a bit because the quality of the thumbnails is uneven.   Click on a thumbnail and you'll be taken to a very worthwhile page of information about that species.   Last visited in March of 2008.
North American Butterfly Association The North American Butterfly Association is the largest organization in North America dedicated to butterflies.   Their website has interesting but incomplete photo galleries devoted to the different families of butterflies which inhabit Canada, the USA and Mexico, as well as links to other butterfly websites, including links to American regional butterfly websites.
Georgia Lepidoptera This website covers butterflies and moths in the south-east of the United States.
World Museum of Natural History When I visited at the end of 2001, this privately owned venture had a gallery of 77 North American butterflies and moths.


Caterpillars
Australia  
Butterfly Larvae of Australia The caterpillar, butterfly and moth section of Don Herbison-Evan's website is slightly uneven, you have to access the butterflies and moths via the caterpillars, but it's still worthwhile and he is a real expert.   Last visited in March of 2009.
   
Costa Rica  
Caterpillars and Parasitoids of a Costa Rican Tropical Wet Forest This is a very well done website, with species pages which include good quality photographs, though quite a few of the links to the adult butterfly or moth are broken.
Janzen and Hallwachs Caterpillars This is the website of a couple of people at the University of Pennsylvania, whose interest is the caterpillars of Costa Rica.
   
USA  
Caterpillars of Eastern Forests This United States Geological Survey website has photo galleries of butterfly and moth caterpillars under the family listings, unfortunately the photos are very small.   There are an awful lot of caterpillars shown here, but of course it's nowhere near a comprehensive collection.   Last visited on 2008/04/18.
What's This Caterpillar  (American section) This British website has several hundred photos of American caterpillars with identifications.   The thumbnails are a little bit small, and I'm not certain that all of the identifications are correct (the American Painted Lady looks more like a smeared dagger moth to me), but this is a very good starting point when trying to pin down an identification.
University of Maryland Barbosalab Dr Pedro Barbosa's website has eight photo galleries showing caterpillars from the eastern seaboard of the USA.   The photos aren't that big, but they're useable.
Caterpillars of North-Western Forests This United States Geological Survey website is very poorly done from a photographic point of view.   Hopefully one day it will become as good as the corresponding Caterpillars of Eastern Forests website, but in the last three years there have been no changes apart from a reorganization which broke many of the links.   Last visited on 2008/04/18.


Dragonflies and Damselflies
USA  
Dragonflies and Damselflies of the United States As with the other sections of the United States Geological Survey website, the photos in the photo galleries are too small and many species aren't represented, however this is still a useful resource for identification.   The front page has state-by-state information as well as an excellent list of links to other websites.   Last visited on 2005/07/13.
University of Puget Sound Odonata Website A website operated by the University of Puget Sound which has links to odonata information for the USA, the Caribbean and Latin America, and other links (but unfortunately, no thumbnails) to good quality photographs (including many macros) of dragonflies and damselflies of North-West America.   Last visited on 2008/04/18.


Flies
USA  
The Diptera Site The diptera (ie, fly) section of the systematic entomology laboratory is pretty much useless to anyone except scientists studying flies who already know the name of the species they're interested in, but the Introduction to Flies section has photos of various fly families, which can be helpful to identify a fly you've seen, and there are more family photo galleries on the Young Dipterists' Safari page.   Last visited in June of 2006.


Mantids
World of Mantids Martin Stiewe's German website is brief and scientifically oriented, but it has a nice gallery of mantids.   Last visited in April of 2009.


Moths
USA  
Moths of North America This website previously operated by the United States Geological Survey website has been folded into the ButterfliesAndMoths.org website reviewed above.
Kirby Wolfe's Saturniidae Collection This is an excellent website featuring the Saturniidae, or giant silk moths, many of which have spectacular colors and patterns.   Although the photos are said to be low resolution, they are far superior to the photographs found on most websites.  The only thing keeping this website from a 5 star rating is that there's no gallery - to view the photos of moths and their caterpillars you have to click on the Latin name.
Web Images of North American Moth Species This frame-based website has links to photos of 6,300 North American moth species.    Unfortunately there is a high probability of bad links, because most of the links on this site point to photographs on other sites.   Originally, to find a photo you already had to know the name of the moth, which made identifying a moth using these photos next to impossible.   The situation has been improved slightly by an identification page for the major families, but this still takes you to the list of species, arranged by family.   Last visited in January of 2008.
Noctuid Search This website seems to be oriented towards moths as plant pests, it has a huge list of noctuid moths arranged by their scientific names, with photos of most of them.


Spiders
International Society for Arachnology This scientific website contains a good list of website links for spiders and other arachnids such as scorpions.

Australia  
Australian Museum Online:  spider fact sheets A very professionally done website with quite a few pages and photos, but not quite comprehensive enough to get five stars.
   
USA  
Spiders on the Web This website should be called by its subtitle, "Spiders of Orange County, California".   There are about 75 photographs of spiders and arachnids here, the photographs are very good and the spiders are mostly ones which aren't limited in range to California.   Last visited in July of 2007.
A Guide to Missouri Spiders About 20 descriptions of spiders found in Missouri, together with small photographs.   Last visited in July of 2007.
Spiders in Ohio This website has a good photo index page which links to pages of photos of spiders ordered by family.   The thumbnails are very small and the linked photos aren't too big, either, but this site is still a good resource for identifying American spiders.
