The flight period of the black-veined white is between April and July.
The adults are quite social and their abundance varies greatly from year to year.
The eggs are laid on the food plant, usually a member of the rose family Rosaceae and often on trees and bushes (Malus domestica, Malus micromalus, Pyrus communis, Pyrus serotina, Sorbus intermedia, Sorbus hybrida, Sorbus aucuparia, Crataegus monogyna, Crataegus oxyacantha, Crataegus jozana, Prunus spinosa, Prunus padus, Prunus ssiori, Betula spp.,
Salix phylicifolia, Chaenomeles lagenaria).

The eggs are laid in groups of 30 to 100.
They take about three weeks to hatch.
The caterpillars tend to remain in a group with a communal larval web.
This species has one generation each year.
The caterpillars overwinter communally in a webbing tent with entwined leaves.
Caterpillars feed close together on the leaves of the food plant at first, before dispersing in the later developmental stages to other parts of the tree.

The pupal stage lasts about three weeks.
