Description

Side view

Dexia rustica can reach a body length of 8.4–12.7 millimetres (0.33–0.50 in) and a wingspan of 16–24 mm.[12] These small tachinids have generally a black thorax, with grayish yellow pruinosity. Four longitudinal black vittae appear on dorsum,[13] Abdomen appears greyish-brown or reddish, with a darker longitudinal dorsal marking, more or less evident. It is cylindric-conic, with two setae among each segment. Probocis is short and membranous.[14] Females usually are darker than males.[15][11] Wings are hyaline, with a reddish yellow tegula and a dark brown basicosta. Legs are reddish yellow.[13]

Biology

Adults can be found from June to August,[11][12] feeding on nectar and pollen, especially of Heracleum sphondylium.[12]

Larvae develop in the soil feeding on beetle larvae (endoparasitism),[11] mainly of Melolontha melolontha,[12] Amphimallon solstitialis, Rhizotrogus marginipes[13] and Phyllopertha horticola (Scarabaeidae).[16]
