Milkweed Longhorns

Hi Kaylee,
These are Milkweed Longhorns or Red Milkweed Beetles in the genus
Tetraopes, a group of beetles in the Longhorned Borer family Cerambycidae.  Milkweed Longhorns are found on milkweed and they feed on the leaves as adults and the larvae bore in the roots of milkweed.   The adults squeak when handled.  More information can be found on BugGuide.  We are postdating your submission to go live during our holiday later in the month.
