Description

Tenthredo amoena can reach a length of about 9–11 millimetres (0.35–0.43 in).[3] These sawflies have a black body with yellowish markings and short antennae, that are about one and a half times the width of the head. The first antennal element is pure yellow. In the males the first, fifth and 7-8 tergites of the abdomen are yellow. The scutellum is often spotted with yellow. Wings show a pale brown color with a long brown pterostigma. In the females the apex of tibiae and tarsi are yellow with black markings. The thighs are pure black.[3][4]
This species is rather similar to Tenthredo distinguenda.
Biology
The adults can be encountered from June through July feeding on nectar and pollen of flowers (especially on Apiaceae species). The larvae feed on leaves of Hypericon species, mainly of Hypericum perforatum and Hypericum maculatum. These larvae are yellow and green with black spots and a yellow head.
