It happens here in Florida too. Also,  I heard of a case where they attacked gas lines on cars (I think at a dealership). Are the beetles attracted to ethanol gas or just gas?  My suggestion was simply to stop using plastics. Sounds like a creative topic to seek funding: how to prevent scolytines from attacking automotive products.

Thought I had seen this before, so I checked with Jim LaBonte:

Yes.  Cnestus mutilatus is documented as doing this in Louisiana (Carlton and Bayless.  2011.  Coleopterists Bulletin 65 (3):290-291).  Also, I was consulted about the same behavior in India.  Those are clearly “barkie buns” protruding from the cans.

Hi Jim,

It seems I remember you talking about a scolytine that does this?

These pictures were sent to me, I have a clue what is making these holes.  What do you think?  Why only red?
