Cephalcia is a genus of Web-spinning sawfly of the family Pamphillidae. Cephalcia abietis is widespread over most of the temperate part of Eurasia, living in older strands of spruce in the foothills and mountains.

The adults fly from the middle of April to the end of June. Research Cephalcia
Neurotoma is a genus of Leaf-rolling sawfly of the family Pamphillidae. Neurotoma nemoralis is widespread throughout Europe, often living in gardens, preferring cherry, plum, apricot, peach, sloe and similar fruit trees where the female lays her eggs. The larvae feed on the leaf tissue, at first living communally and later dispersed, hidden in rolled up leaves, later still communally again in a large nest made of the rolled leaves sewn together. The larvae are voracious and can defoliate an entire tree. The adults fly from April to May. Research Neurotoma
