Flower Longhorn Beetles from the genus Strangalia have tapered bodies and are frequently found walking among the petals of flowers.
Strangalia luteicornis, like its cousins, has broad 'shoulders' and an abdomen that gets narrower, or strangled, down the length of the abdomen. Large black and yellow spots on the elytra (wing covering) connect forming bands across the body. The pronotum is orange with two black stripes running from head to abdomen. This species of Flower Longhorn Beetle visits flowers as an adult to drink nectar from the blossoms. It is also an accidental pollinator, which benefits gardens and meadows. Its larvae, however, bore into tree trunks, which can hinder the tree's ability to move water and nutrients over time.
