biology

Biology. Habitat: forest margins, clearings and gardens with sun-exposed dead wood. Adults fly near sun-exposed dead tree trunks (e. g. Betula, Populus, Quercus), and near walls of wooden buildings (e. g. log barns, sheds), poles and log piles. Flight period: late May to September. Host: Ancistrocerus trifasciatus (Mueller) (Vespidae) (Paern et al. 2014, our own obs.). Possibly also Ancistrocerus gazella (Panzer) and Ancistrocerus nigricornis (Curtis) (Schneider 1991).

diagnosis

Diagnosis. Length 6 - 10 mm. The head and mesosoma are dorsally dark blue, violet or nearly black, and the punctures of the mesoscutum are usually of the same colour as the interstices. The tergites are golden red and the sternites variably golden or greenish (Fig. 131). The punctation of T 3 is often characteristically dense and homogeneous. The body shape is more elongate than in Chrysis ignita, Chrysis impressa and Chrysis borealis sp. n., but not as slender as in Chrysis angustula and Chrysis leptomandibularis. Females are usually best distinguished from other species of the Chrysis ignita group by their thin and basally concave mandible (Fig. 143), though males are more difficult to identify. Compared to Chrysis impressa and Chrysis borealis sp. n., the mandible of male is slightly thinner and basally more concave (Fig. 148), the body is more slender, and the relative length of F 1 to F 2 is somewhat smaller (Fig. 176). Identification of the males is not always possible with certainty by morphological characters alone.
