Very little is known about the biology of the chalk-fronted corporal. Its flight season runs between mid-May and late October (3), although in California it is mostly seen between June and August (2). This species forages in open woods, perching on the ground and in low vegetation (3). As with all dragonflies, it can be assumed that the chalk-fronted corporal is a highly skilled predator and detects its prey mainly by sight. All dragonflies are opportunistic and generalised predators, with small flying insects being the primary component of their diet (5).
The male chalk-fronted corporal is highly territorial (2). When a female dragonfly enters the male’s territory, the male chases the female and then forms a ‘wheel’ position. This is a characteristic position formed by all dragonflies during copulation, which consists of the male grasping the female’s head with a claw-like appendage at the base of its abdomen. Egg laying follows shortly after copulation, with the female depositing the fertilised eggs into water. Female dragonflies are able to store live sperm in their body for days and any new copulation may displace the sperm from the previous mate, so many male dragonflies defend the female until the eggs are deposited (5).
The eggs of dragonflies hatch into aquatic larvae, which are voracious predators and possess extendible mouthparts with hooks on the tips. When the mouthparts are extended, these hooks grip the prey and return it to the mouth. The larvae eventually metamorphose into the adult form (5).
