Superfamily Tenebrionoidea (Fungus, Bark, Darkling and Blister Beetles)

Per Texas A&M Entomology Dept.:

“Tumbling flower beetles can be very abundant on flowers especially those in the carrot family (Umbellifera) and aster family (Compositae). The larvae feed in stems and dead wood. The pointed tip of the abdomen gives the family a second common name, the spinetailed beetles.”

Two prominent dots on the rear, completely black face.

CENTRAL FLORIDA CRITTER OF THE DAY:  Cottonwood Leaf Beetle (Chrysomela scripta)

Oh how I wish this guy (gal?) was feeding on this invasive cogon grass.  Wouldn’t that just be a win/win.  Unfortunately, I believe it was just resting probably looking for a member of the Populus genus (Cottonwood) from which it derives it common name.  Other hosts include Willows (Salix spp.)

“Infested trees rarely die from cottonwood leaf beetle defoliation.”
“Handpick beetles off trees if possible.”
