Ship-Timber Beetle

I was not able to get an ID on the spider I took the pictures of, but the bug was what I really wanted an ID on. It was annoying, noise, and it was the estrange way it flew, strait not horizontal that caught my attention, I also was wondering how it could fly with such high (close to head) small wings?

Atractocerus species are rarely encountered and therefore, not well studied. Their evolutionary history is still unknown; however, the oldest known lymexylid fossil is a very primitive member of the genus Atractocerus preserved in 100 myo Burmese amber (Grimwold & Engel 2005). Thus, the lineage containing these beetles had already appeared by the mid-Cretaceous and may have originated as early as the Jurassic, a fact that has earned them the moniker ‘living fossils.’ These beetles were once thought to be among the most primitive of all Coleoptera – their simple wing venation, almost undifferentiated antennae and tarsi, and naked abdomen being likened to a supposed neuropteran common ancestor.”
