116 White Satin Moth (Leocoma salicis)
Found in half shady, damp locations, such as forest edges and hedges with their food plants, but also in avenues, parks and gardens. They are common, but only occur in small numbers. Leucoma salicis is also reported from outbreaks (population explosions), but these are known only from historical times.
The larvae feed on Salix and Populus species. Pupation is in a loose cocoon between leaves, the pupa being glossy black with white spots and yellow tufts or hair. The moth appears in June, July and August. The males already begin to fly before dusk in the evening and often swarm like snowflakes round the poplars and willows at country roads.
