Insect on pitcher plant - Arge abdominalis

Insect on pitcher plant - Arge abdominalis
An acid wetland along hwy 130., Columbus County, North Carolina, USA
April 23, 2007
Size: approximately 1.5cm long
This insect was restricting itself primarily to crawling around on the developing leaves of a pitcher plant (Sarracenia flava), in an acidic wetland. The image was taken around 3pm on an overcast day.

Moved from Argid Sawflies.

Arge abdominalis (Leach)
Larvae feed on rhododendron. No Arge known to feed on pitcher plants; probably just resting there.



Moving to family page for now...

This is a sawfly, a type of stingless wasp that is vegetarian in its larval stage. This one might either be in the family Argidae or the family Tenthredinidae. Hard to tell conclusively from this image alone.

Sawfly ID
My, you're speedy! Do you know if these are generalists or specific on the species they eat. I want to know if this is a species associated with Sarracenia. Thanks!

I don't know.
I doubt it is associated with the pitcher plant, but I'm not really qualified to say so with any degree of definity. You could query Dr. David R. Smith at the SEL at the Smithsonian. He is an authority on sawflies and related wasps.
