Title: Which beetle?
Post by: Don P on April 07, 2019, 05:55:28 PM
These guys have just hatched out. This is RO I sawed about a week ago. Which one is it? They are ~1/32", my eyes couldn't see any of this detail in real life. It looks like there are 2 ovipositor egg holes in the pic, left and right of the insect? We've warmed up into the 60's and are pretty much out of freezing weather. We've been borating and burning debris this weekend, the bugs are waking up from their winter slumber.

As the lyctid powderpost beetle likes under 15%MC, and you just sawed this lumber, it must be a different insect. Or maybe it is just passing through and not in the wood.  A wild guess is a bark beetle.

It doesn't match pictures of lyctid or anobiid from what I can tell. There were a number of them on the boards. Some type of bark beetle does seem the most likely. My "egg holes" must be just random cell ends showing up in the pic.
