scientific name    Agulla    

common name     Snakeflies

habitat
Arboreal, some tree or bush cover necessary.

identification
As an order or superfamily, depending of the classification, Raphidioptera are very easy to distinguish, due to their long 'necks' which are actually an elongation of the first segment of the thorax. They have large clear wings with brown or dark brown veins and many crossveins. The family Raphidiidae is distinguished from the other family, the Inocellidae by the presence of three ocelli, where the Inocellidae have none and a transparent, rather than opaque pterostigma on the front edge of the wings. As Agulla is the only genus of Raphidiidae found in Alberta, it is rather easy to identify.

life history
Members of Agulla spend at least a year as larvae, with pupation occurring in the spring and lasting three weeks at most (Asp÷ck, 2002).

conservation
Raphidiopterans in general are thought to be fairly rare, and they are less common in the Nearctic than the Palearctic, so Agulla is unlikely to be common.

diet info
Agulla are carnivorous and the adults feed mainly on aphids and other similar insects. The larvae are also carnivorous and feed on the eggs and larvae of other insects, especially Lepidoptera, Hymenoptera, and Coleoptera (Asp÷ck, 2002).

range
Agulla is a fairly widespread genus, occurring mainly in the Northern Hemisphere, though species are found farther south in Africa and Mexico at high altitudes (Asp÷ck, 2002).
