Asteroid Caterpillar (purple)

Cucullia asteroides


Approximately 1 1/2 - 1 3/4 inches. Purple Goldenrod Hooded Owlet Moth Caterpillar. Feeds primarily on Goldenrod or Aster. Leaves and flowers


Meadow in the Poconos


I tried to correct a problem with the color due to it was set on indoor instead of sunny outdoors. Photo is not color enhanced. I found 3 or 4 green asteroids, 1 purple, 1 red, and 1, possibly 2 yellow.

Beautiful caterpillars!

Stranger yet, I did a google search on yellow asteroid Caterpillars and no one seems to have a photo except mine here at Project Noah. Same with the red one. That is weird. Still searching though.

Love the stripes on this! I like your second photo the best. That's cool that you find so many of these.
