This tiny monstrosity (~2mm in length) was inside of some kind of "flat tent cocoon" on a pepper plant leaf in Washington state, USA.

Not sure what's going on here. Is it malformed or infected?


  • $\begingroup$ Could you please attach an image of the "cocoon", it should be helpful $\endgroup$ – Algae Jan 5 at 19:53
  • $\begingroup$ @Algae I don't have the image, and now the "cocoon" is destroyed. It looked like a flat round bit of insect silk on the leaf, the insect was in the center under the silk, thus giving it slightly "tent" appearance. $\endgroup$ – Sergii Dymchenko Jan 5 at 20:09
  • $\begingroup$ @SergiiDymchenko did the cocoon look like this or like this? $\endgroup$ – theforestecologist May 3 at 6:04
  • $\begingroup$ Also, is that "fluffy" lookign stuff in the rear of the insect simply rolled-up "cocoon" or did it appear to be coming out of the insect's abdomen? Could you describe its texture? $\endgroup$ – theforestecologist May 3 at 6:08
  • $\begingroup$ @theforestecologist the cocoon looked more like the first example you posted. The fluffy stuff looked like it was growing from the abdomen, it was rigid and looked a bit like fungus (but probably not fungus). I was suggested elsewhere that this is a failed to develop micromoth pupa, and the stuff is hairy larval skin. $\endgroup$ – Sergii Dymchenko May 3 at 8:25
