Milkweed Tussock Moth Caterpillar

Just happened on to your site a couple months ago, and have been raving abt. it to anyone that will listen!!! Great job and service you do. Now, for my bug, er, caterpillar…I found him eating my butterfly weed the other day, and I’m thinking he must be a pest. I brought one of the larvae in when I first found it and it immmediately spun a cocoon…now I’m wondering if I should get rid of it….can you tell me what this is going to be? Thanks, in advance, for your great service!

Hi Pat,
This is a Milkweed Tussock Moth Caterpillar or Milkweed Tiger Moth Caterpillar, Euchaetes egle. If the caterpillars are plentiful, they may defoliate the host plant. The adult moth has unmarked grey wings and yellow spots on the body.

  1. Are they hard to get rid of ? I grew milkweed to attract a monarch and these are eating the plants with a ferocious appetite. Do they eat other plants? Any suggestions.
