Species profile: Ceraclea fulva

January 7, 2017

Ceraclea fulva (Rambur, 1842)

Ceraclea fulva is one of 24 members of the Family Leptoceridae found in Ireland, and one of six members of the genus Ceraclea. It is a species whose larvae can be found in large ponds, lakes and slow rivers, on a substratum of sponges on rocks and woody debris, in standing water. The case of Ceraclea fulva is made of secreted translucent material and sponge spicules, often incorporating fragments of living sponge. The species has no preference in terms of water pH, and can tolerate brackish water.

In temperate areas, Ceraclea fulva has a univoltine (one generation per year) reproductive cycle, and lives for up to one year. The larvae feed on sponges.

Defining features of the larvae of Ceraclea fulva include a mesonotum with dark, curved posterior-lateral projections, mandibles no more than twice as long as wide, a quadrangular ventral apotome (though small larvae may have a squat, rounded triangle-shaped apotome), mesoventer with at least two setae on each side, pronotum pale with dark band along the anterior edge, and anal proleg claws with two accessory hooks.

The adults of Ceraclea fulva can be found on the wing from June to September.
