So, loopers like rosemary!

I've always been under the impression that rosemary isn't a host plant for pests (like caterpillars, moths, etc.) because it never seems to be listed. It seemed that the strong fragrance might be a deterrant.

So imagine my surprise to find a looper caterpillar sitting inside my rosemary plant. The next day - looking deeper - I saw an adult/moth, and a pupa cocoon. They all seem to match up with soybean looper pictures. Since there really aren't any flowers around, I bet the perpetual fragrance stands out, and attracts them.

RE: So, loopers like rosemary!

Some larvae moth and butterfly species are dietary generalists, and the adults are free to deposit the eggs on most kinds of vegetation.

Fragrance might be something of a deterrent for mammals, but I really suspect that it is the strong oils (and taste) of rosemary that keeps many insects (and the four legged pests) away. I have found, however, spider mites, whitefly, and beetles on rosemary.

Deer and rabbits seem to avoid it, though! ;-)
