Pediciidae - Hairy-eyed Craneflies



NEMATOCERA, Tipulomorpha, Tipuloidea

Number of British species: 19

Size: M-L

Difficulty: 1-2

Scheme: Covered by the Cranefly recording scheme


Nematocera varying from medium sized (5 mm in Dicranota, subgenus Paradicranota) to very large (35 mm in Pedicia). Antennae, wings, legs and abdomen long and slender. Ocelli absent; eyes pubescent, with ommatrichia in between the facets; antenna with 12-17 segments. Thorax with a V-shaped transverse suture. Wing with 2 anal veins, wing in some cases with a characteristic pattern.


The larvae of the genus Ula feed on mushrooms and bracket fungi; all other larvae, as far as known, are aquatic to semi-aquatic and prey on worms, insect larvae, mites and other small invertebrates. Predatory larvae are mobile and rapidly moving; because of their massive head capsule they are not able to swallow large prey as they are but have to tear them to pieces. Of the three more common genera, the larvae of Tricyphona are found in diverse wet and semi-aquatic habitats (from the shores of springs, streams and lakes to bogs and forest litter in wet places), those of Dicranota tend to occur along and in running waters but develop also at the shores of standing water bodies; larvae of Pedicia are restricted to running water of wells, brooks and small rivers. Pupating takes place inside a silken tube. Adults are found in an array of moist habitats.
