Bug of the Week: Cabbage Looper Eggs and Thrips

Our penstemons have been flowering.

Nectar from these flowers are a favorite food of hummingbirds and all sorts of bees.

A few days ago I also noticed some eggs on the flower petals.

They are the eggs of the cabbage looper moth. We've seen them in the yard before.

What is that sliver-like thing that is walking over the eggs?

It is a thrips!

Different species of thrips feed on a wide variety of items, including flower pollen and insect eggs. I'm not sure whether this one was feeding or not.

In any case, the eggs had all disappeared the next day. They may have hatched or they may have been eaten.

Who knew so much drama could occur within a single flower?

Do penstemons grow where you live? Are they blooming yet?

  1. We actually have a lot of different kinds of penstemons here- I probably have 3 different types planted in the yard. They seem to do very well and remain somewhat evergreen.

  2. Hi Roberta,

    I recently noticed similar eggs in a very geometric pattern on the leaf of a pink Dahlia bloom in our garden here in Flagstaff, AZ. You say there are from the Cabbage Looper Moth… should I leave them there or get rid of them (are they a pest)? I'd be happy to email you a photo - it is a very precise pattern on the leaf - fascinating! Thanks for this post!
