Biology

Habitat: Abies, Picea and Pinus conifer forest and conifer plantation, montane Betula woods.[12] Arboreal, but descends to visit flowers of Caltha, Crataegus, Crepis paludosa, Euphorbia, Fragaria, Frangula alnus, Galium, Heracleum, Hieracium, Lonicera xylosteum, Prunus spinosa, Ranunculus, Rosa rugosa, Salix repens, Sorbus aucuparia and Stellaria.[13] The flight period is April to June and July (later at higher altitudes or more northerly latitudes). The larva feeds on aphids.
