Phyllonorycter blancardella F

This generally abundant moth is a minor pest of apple. The larvae form blotch mines in the leaves, and these distort the lamina. This species is a particularly damaging orchard pest in continental Europe and North America.


First-generation adults of this bivoltine species emerge in May. Eggs are laid on the underside of leaves and hatch 2-3 weeks later. Larvae mine singly within the leaves for 5-6 weeks. Each larva then pupates within its mine. A second flight of adults appears in August but sometimes earlier. Their progeny overwinter as pupae within mines on fallen leaves.


Adult 8-9 mm wingspan; forewings dark copper-brown with brilliant white, dark-edged markings (Fig. 272); hindwings dark grey. Larva up to 5 mm long; body yellow and translucent; head pale brown.
