A handsome member of the scarab family, this rather large beetle showed up on the side of my garage. They eat wild and domestic grapes and Virginia creeper, although the damage they cause is so minor that most authorities suggest it’s not worth bothering controlling them. As we have no domestic grapes here, I’ve got no reason to worry about them.
The larvae eat rotting hardwood underground, and are considered somewhat beneficial as a result, since they’re breaking down diseased stumps and dead tree roots and whatnot. All in all, this bug is neither particularly good nor particularly bad, but they are certainly quite pretty as beetles go. (They also, for unknown reasons, sometimes fill Japanese beetles with unspeakable lust. Japanese beetles are much smaller but will attempt to mate with what must appear to them to be a GIGANTIC FEMALE SEX-GODDESS. There is no word on how the grapevine beetle feels about this, but this leads to some people thinking these are, in fact, giant Japanese beetles and killing them as a result, which is about as sad a case of victim blaming as one can imagine in the insect world.)
One word of caution—this beetle is very docile but has very sharp feet. If you pick one up and handle it, you may get stabbed, a circumstance probably as upsetting to the poor beetle as to you.
