Explanation of Names

From Latin penna a feather, or a wing (1).

Size

circa 19 mm length, 33 mm wingspan (guide photo measurements)

Life Cycle

Trogus pennator is a parasitoid of swallowtail butterflies (Papilionidae), ovipositing in the caterpillars.

The solitary larva develops inside the caterpillar, allowing it to pupate before killing it. After metamorphosing, the adult wasp chews an irregular hole in the chrysalis to escape.

Remarks

Perhaps a mimic of well-armed spider wasps, such as Tachypompilus ferrugineus:
