What are these insects and should I be concerned? They're about 1/8" in length and don't look like termites or pine beetles. I don't see any insect-related damage to the wood but they seem to have a strong affinity for the wood (they're no where else to be seen).
The boards are kiln dried SPF and hem-fir which have been sitting outside for about 6 weeks now under a tarp and the bugs only appeared within the last week.
