Sapyga similis is a hymenoptera from the family of the club wasps (Sapygidae).
features
The wasps have a body length of 9 to 13 millimeters (females) or 8 to 13 millimeters (males). The females have a black body, in which the first three tergites are completely or partially, the underside of the antennae three to eight, the rails ( tibia ) and the tarsi are colored red. There are yellow spots on the inner edges of the eyes, the temples, the pronotum , tergites three, four and six, the base of the anterior splint, and occasionally also on the third and fourth sternite. The protruding edges above the sensor bases butt against each other. The males are black. The feelers are red on the underside and partly also on the top. The frontal plate ( clypeus ), the inner eye rims and the tergites and sternites on the third and fourth segments are spotted yellow, the splints and tarsi are completely yellow. The eighth to twelfth antennae are one and a half times as long as they are wide. As with the females, the edges meet over the antennae bases.
Occurrence and way of life
The species is common in Europe north to south of Sweden. The animals fly from late April to late September. The larvae are parasites of the bees Osmia nigriventris and Osmia uncinata . The fact that they also parasitize on Osmia robusta , as claimed by some authors, is questionable because of the small size of the wasps.
