[MAIPC] FW: Photos from todays outing

[Marc Imlay]

The habitat stewardship Sierra Club interns who just discovered this aphid greatly impacting Japanese Stiltgrass would like us to determine if it is a useful biological control of Japanese Stiltgrass. Cheers.

We found this on Japanese Stilt grass today. Can anyone ID it. It is very sticky and we transferred some to a patch nearby that we are not removing to see what happens to the stiltgrass there.

I can’t get a perfect picture here, but…it really looks like they have crushed a bunch of aphids in different life stages and spread them. 

Aphids are these colors, and sticky. Could that be the case? Or is it more complicated than that?

Hey I think Andrew is right. They are probably aphids but I can’t get it to species. Aphids are significant pests in some cases so there should be literature out there that would allow you to key it out by species, if you were willing to go down that rabbit hole. It’s possible you can google the plant host and aphids and see if there is a species that only eats that plant. 

 

I hope this helps

Aphids? Although I’m not sure how to identify them further than that.

I concur with Carole. It looks like aphids and the stickiness makes sense from the "honeydew" they excrete.

Is that it, or is this too elementary a solution?
