Pictures/sketches of (cowpea) curculios

anney(Georgia 8)April 18, 2010

I don't think I've ever seen one of these insects, but they should be easy to ID, given their unique characteristics -- Cowpea curculio or Chalcodermus aeneus. They are kin to weevils. They feign death and drop to the soil when disturbed. Beetles rarely fly. Adults overwinter in the soil and under leaves and other organic debris.

"....red imported fire ant[s], Solenopsis invicta Buren (Hymenoptera: Formicidae), significantly reduced the rate of successful pupation by cowpea curculio", so if there's anything to praise the fire ant for, I suppose it must be its predation on the cowpea curculio!

Bump down.

Anyone who runs into this critter can do a GardenWeb search to see these pictures, which was posted FYI.

Thanks anney, I have seen that critter before and did not know what it was. My purple hulls rarely see any damage until late in the season after we get our fill. Then I till in and plant a patch of hairy vetch for the winter.
