Allantus is charcterised in the Allantini by having a hind wing with neither an enclosed middle cell or peripheral vein. In the forewing, the anal cell is complete and with an oblique cross-vein. On the underside of thorax, the propleurea meet with a broad connection. The antennae, which are nine-segmented, have the eight antennal segment is almost three times as long as the breadth at the apex of that segment. The post-genal carina extends beyond the top of the eyes almost as far as the post-occipital area.

Allantus is primarily a Eurasian genus with a few species located in the Americas. There are 10 species listed in Britain, four of which are also recorded in Ireland. The adults are slender bodied and often with a white or yellow band on one of the tergites. The larvae are free living and on maturity tunnel into twigs and stems to overwinter.
