Hi Daniel,
This tiny bug was on a Mexican Milkweed leaf in the back today. Do you know what it is?

Unknown Beetle on Milkweed

Case Bearing Leaf Beetle on Milkweed

Hi Anna,
This is not a True Bug.  Because of the larger number of antennae segments, this can be identified as a beetle, but it doesn’t really look like a Leaf Beetle.  We will try to research this more later.

Thank you, Daniel.  Any help you can provide will be helpful.

We will try to get some assistance from Eric Eaton.

Hi, Daniel:
It actually *is* a leaf beetle, one of the case-bearing (as larvae) leaf beetles in the Cryptocephalinae subfamily.  This is probably a species of Pachybrachis.  Nice image considering how small they are.

Daniel & Eric,
Thank you for this identification.  Got a new camera and am pleased with what it can do!
Anna
