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.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Antennae: Beetles have a pair of antennae on the head used as sensors.
Head: The head is home to the insect's eyes, antennae, and mandibles (jaws).
Thorax: Holds the three pairs of legs as well as vital internal organs.
Elytron: One of two wing cases on a Beetle that protects its wings (plural: elytra).
Wings: Appendages used for flying and kept under the elytra until needed.
Abdomen: Houses organs related to circulation, reproduction, and excretion.
Legs: Beetles have three pairs of legs located at the thorax, numbering six legs in all.
