Outside resources

As I note elsewhere on this site, the information I provide here is almost entirely my own observations of aphids with the very best identification I can accomplish and that I think is somewhat meaningful (some groups have terrible species-level taxonomy, making identification to species meaningless at best, misleading at worst).  There are two absolutely amazing online resources I use to aid in identification (in combination with original literature) and get the currently accepted names.  These sites are:

Aphids on the World’s Plants, by R.L. Blackman and V.F. Eastop

and
