We found a swarm all over the side of the garage. Tree in backyard split and thought that might be where they came from.

Black Margined Loosestrife Beetle

Hi Claudia,
We are certain that this is a Leaf Beetle in the family Chrysomelidae, however, we have not been successful identifying it to the species level despite the extensive archive on BugGuide.  The closest matches we could find were the reverse coloration of
Neolema ovalis (see BugGuide) and Phyllobrotica limbata (see BugGuide), though we are quite confident that neither of those is correct.  Perhaps one of our readers will have better luck or notice something on BugGuide that we overlooked.

Thanks for the challenge!

Thanks Eric,
We were most pleased to read this:  “Imported as a biocontrol to combat purple loosestrife (Lythrum salicaria)”
on BugGuide.
