Here are some links that I visit regularly in my natural history work. (Please note that I am not interested in suggestions of other links to include here; these are just some sites that I have personally found useful.)
BugGuide.Net — The general ID Request page is here, and I manage the following pages:
- Master List of Online Taxonomy References
- Unidentified Leaf Mines
- Unidentified Galls
- Arthropod Pathogenic Fungi
- Wingless Adult Insects
HOSTS – a Database of the World’s Lepidopteran Hostplants – This database is full of misinformation, like the books on which it is based, but it is still a good place to check when looking for a list of suspects when trying to ID a caterpillar on a particular plant.
Lepidopteran Use of Native & Alien Ornamental Plants – A downloadable database that adds to the HOSTS database and makes some corrections to it. It includes an extremely important Literature Cited section, which the HOSTS database does not.
USDA PLANTS Database – Taxonomy is not always up to date, but this site is great for looking at geographic ranges of plants, or getting a list of plants of a particular family or genus found in a given state.
The Biota of North America Program: North American Vascular Flora – Another source for plant distribution data, with nice county maps.
MicroLeps.org – Terry Harrison’s informative and well-illustrated guide to the tiny moths of Illinois.
Imperial Measures of Length – I have to check this page occasionally to remind myself that when 19th century authors talk about “lines,” they’re referring to 2.12 mm increments (12ths of an inch).
The list below is salvaged from my old website. It is somewhat redundant with the list above, and I haven’t gone through it yet to weed out broken links, but it may still contain some useful things.
