Distribution

Habronyx species are found in most realms, with the exception of the Afrotropical realm.[2]

Reproduction

Habronyx adults lay their eggs inside Lepidopteran larvae (i.e. caterpillars) by piercing them with their ovipositor.[2] Habronyx eggs consist of an equatorial disc and a caudal stalk, making them look a bit like the cartoon oil lamp from Aladdin.[3] It's thought that the shape is adapted to attach the egg to the inside of the caterpillar's integument.[4] Once the eggs hatch, the Habronyx larvae consume the caterpillar from the inside. They emerge from the deceased caterpillar as adults.

Description
Habronyx eggs consist of a disc and stalk, not unlike this cartoon lamp (sans handle)

The adult of most Habronyx species are generally about 30mm in length.[3]

Like all ichneumons, the genitals of the male Habronyx consists of a capsule formed by two lateral gonosquamae. The membraneous part of the aedeagus is covered in small spines; Habryonx shares this feature with several other genera but some genera have a smooth aedeagus .[3]
