A broad bodied chaser

A male broad bodied chaser at the Dog Pond, seen and photographed by Ian Bushell last week.

Here is the female that Ian photographed last year. The presence of both male and female means that there is a high chance that the species is resident in the park and that they breed in the Lambrok.

Broad-bodied chaser adults are quite long-lived for Odonata: they can be seen from May until even early September. They mate on the wing and the female immediately lays her eggs in the weedy margins of still water like the Dog Pond. She jabs her ovipositor into the water repeatedly, depositing one egg at a time, while the male guards her.

After about two weeks, the eggs hatch into nymphs, the Odonata larval stage, which live in the water for at least a year, sometimes as much as three years, depending on water temperature and food availability. The nymphs grow through several moults into fearsome pond-bed predators, large enough to catch and eat tadpoles and even small fish.
