Legner E.F. Principal groups of insects with emphasis on parasitoids & predators
"For teaching purposes only; do not review, quote or abstract"
All in all, good and apparently up-to-date info under the 'Habits' or 'General Characteristics' or 'Overview' links; especially valuable are the profiles (with ref. lists) of minor/obscure/exotic groups on which very little info is available online otherwise (i bumped into the site looking for info on Monomachidae).
The interface is a bit awkward, the links other than those indicated above are mostly dead (incl. 'Home'), and some underlined/bracketed subtitles that look like links are confusing; also, it took me quite some time to figure out the author, [url=http://facultydirectory.ucr.edu/cgi-bin/pub/public_individual.pl?faculty=4034]Prof.
