Raspberry Crown Borer Moth

Pennisetia marginata


Black with yellow bands, these moths are excellent wasp mimics. They can easily be confused with a yellow jacket until you get a closer look and see their fuzzy body and long, curved antennae. The male is the smaller of the two, with a wingspan of 18-25 mm and pectinate antennae. The female has a wingspan of 25-37 mm and simple antennae.


This couple was honeymooning in my blackberry patch.


The larvae bore into the stems of blackberry and raspberry plants where they can do a lot of damage. In most areas, their entire life cycle takes two years to complete. Adults are diurnal.
