Do you know what wood boring insect this is!?

Prince George's County Maryland

Expert Response

These are old (and possibly disused) Carpenter Bee nest tunnels. The wood is missing in those areas due to woodpecker activity, as they heard the bee larvae inside and tried to peck them out to eat. (It seems they were at least partially successful.)
