Description

Meringopus calescens can reach a length of about 16 millimetres (0.63 in) in females and about 15 millimetres (0.59 in) in males. These relatively large Ichneumonid have a black head and a well defined clypeus, with some heavy punctures. Thorax is black and sculptured. Mesoscutum is polished, with irregular punctures. Wings are quite infuscate. Legs show black coxae and trochanters, but the remaining parts are orange. Abdomen has a mostly fuscous 1st segment, 2nd and 3rd segments are orange, while the apical segments are mostly black. Ovipositor is slightly upcurved and can reach about 5 mm.[4]

Behavior

These ichneumonid wasps have been observed apparently attempting to parasitize the sphecids Ammophila sabulosa and Podalonia affinis, but they also parasitize Saturnia pyri.[2][5]
