Drepanaphis - Female
Plymouth Rock, Winneshiek County, Iowa, USA
September 15, 2008
Size: 2- mm
Drepanaphis acerifoliae, identified by D.M. Lagos, PhD candidate, U of Illinois (MANY THANKS).
She says: "Smith and Dillery (1968) stated that Acer saccharinum, silver maple, is the major host plant. Also A. rubrum, red maple, and A. saccharum, sugar maple, are in their list as host plants of Drepanaphis acerifoliae." The reference she used is "The genus Drepanaphis Del Guercio (Hoptera: Aphididae). Ann. Entomol. Soc. Am. 61(1): 185-204.
Collected in a Malaise trap, Aug 24 to Sep 15, 2008, set in a woodland, with many hard maples.

Moved
Moved from Painted Maple Aphid.

D. acerifoliae has dorsal abdominal tubercles I and III long and fingerlike, II and IV shorter. Maybe it's just the angle here, but this just doesn't look like what you see on D. acerifoliae. Looks like I and II are subequal.

Here's a good example:

Clarification
Sugar maple is Acer saccharum; silver maple is Acer saccharinum. Which is the major host of this species?

 
Sorry about that..
I should have comprehended what I cut and pasted. I'll bet it's supposed to be saccharinum but I'm emailing Doris now. Thanks.

Moved
Moved from Aphids.

Almost appears Albino?
Even though it does exist in insects (right?) it is quite amazing. Nice find, unfourtunately I can't really help you with the species or the dorsal protusions; they do not appear in any of my aphid photos.

 
It started
with this one from a different location. I'm sending both off to IL hopefully for more information.
