Locust Borer
A striking yellow-and-black wasp mimic that attacks black locust trees in North America. Adults appear in autumn and are commonly found on goldenrod flowers. Larval boring weakens locust trunks and can cause breakage.
Did You Know?
Adults synchronize their emergence with goldenrod bloom, making autumn fields their primary mating arenas.
Violin Beetle
An extraordinarily flat beetle shaped like a violin. Its paper-thin body allows it to squeeze between bracket fungi and under bark. Found in Southeast Asian rainforests.
