Your letter to the bugman: I thought you might like a photo of a Tyria jacobaeae (Cinnabar) moth caterpillar, a species introduced into North America to help keep it’s host plant, Tanacetum vulgare (Tansy ragwort- flower shown in photo) from over-proliferating.
Tyria jacobaeae is used in conjunction with Longitarsus jacobaeae (the Tansy ragwort flea beetle) for Tansy population control.
Although Tyria jacobaeae will feed on a couple of native plant species, it is my understanding that the frequency of this occuring does not seem to be of concern.
