Bidigitus platani
western sycamore sawfly
Bidigitus platani is a sawfly species in the family Tenthredinidae, commonly known as the western sycamore sawfly. The species name indicates an association with sycamore trees (Platanus species), particularly western sycamore (Platanus racemosa). As a member of the sawfly suborder Symphyta, adults are wasp-like in appearance but lack the constricted waist characteristic of many other Hymenoptera. Larvae are herbivorous and feed on host plant foliage.
