and 9; they appear as a stylized mask, two eyes a nose and mouth.

Female: - The all black legs are diagnostic when distinguishing between Common and Ruddy Darter females. This female also lacks the prominent vulvar scale bridging the abdominal joint at segment 8 & 9. The saffron colour at the wing roots mimics the male.

Status: - Where found, it can be locally common. In England it occurs mainly east of the Bristol Channel and south of the Humber Estuary.

Habitat: - It has a preference for shallow nutrient rich still and ephemeral water bodies which possess an abundance of emergent vegetation. It will tolerate the brackish conditions found in coastal ditches and pools.

Flight period: - Late June to the end of October.

General: - Both sexes can be found well away from water, perched on suitably high vegetation, from which they hunt for food. It is unclear if males are truly territorial but they do have a comfort zone, which if

intruded upon will stimulate an aggressive response. Coupling usually takes place at a suitable breeding site. Copulation is fairly rapid and in vegetation some way from the waters edge.

The laying of eggs generally takes place in tandem with the male selecting the oviposition site usually close to shaded vegetation.
