Distribution and habitatEdit

This species is distributed across parts of the Palearctic – Europe (including Sicily and the Azores), Russia, and Asia (Israel, Turkey, and Iran).[2][3] These flies mainly inhabit deciduous forests and woodland, especially spruce forest edge.[4][5]



Phaonia pallida can reach a length of about 5.5–7.9 millimetres (0.22–0.31 in). These flies have an orange body with a very hairy thorax.[4][5] The antennae are composed by three articles and bear a feathery arista. The legs and the balancers are yellow, while the tarsi are black. The eyes are dark red, separated by a yellow marking in the females, while in males they are very close to each other.[6]


Adults fly from May to September, feeding on nectar of flowers (especially of Heracleum sphondylium).[4][5][6] Its larvae have been found growing in various fungi (Amanita rubescens, Clitocybe nebularis, Paralepista flaccida, Xerula radicata, Hymenopellis radicata, Amanita muscaria) [6] but also in rotten wood and under tree bark.[5][7] The last larval instar of Phaonia pallida is carnivorous, feeding on small insects.[5][8]
