The red and yellow Banded Longhorn Beetle likes visiting flowers, but it really digs trees.
Banded Longhorn Beetles are members of Cerambycidae, so they have extremely long antennae (horns) like their other relatives. Their bodies are colored in alternating bands of red and yellow. The head and pronotum are black. A thin band of yellow separates the pronotum from the head and abdomen. They are wider at the 'shoulders' and taper at the tip of the abdomen. Antennae are black and segmented. Legs are yellow with black 'feet'.
They are often found on flowers, eating the pollen of a variety of species though they seem to favor parsley, carrot and celery flowers. Look for them in herb, vegetable, and flower gardens. Adult beetles can also be found on hardwood trees. Eggs are laid on dead or decaying trees where larvae hatch and begin boring into the wood. Look for larval frass, a mix of feces and sawdust, on the trunk or near the base of the tree. It is produced as a larva digs and is expelled as the tunneling deepens. This species' larvae seem to prefer birch, sumac and goldenrod. Examine fallen trees and rotting logs in mixed wood forests for signs of the Banded Longhorn Beetle.
