Cydia fagiglandana, the beech moth, is a moth of the family Tortricidae.
Distribution and habitat
This species is present in most of Europe. [3] These moths mainly occur in beech woodland.[4]
Description
Side view
Cydia fagiglandana can reach a wingspan of 12–16 mm.[4] The forewings are brown-black irrorated with whitish, crossed by pairs of fine dark brown stripes. The basal patch is slightly darker, the edge sharply angulated. There are two leaden-metallic streaks from costa posteriorly and a large darker coppery-tinged terminal patch hardly reaching costa. The ocellus within this patch is edged with leaden-metallic, enclosing some blackish marks. The hindwings are fuscous. The larvae are light yellowish or whitish, longitudinally clouded with orange; spots orange; head pale brownish; plate of 2 pale ochreous.[5] This species is rather similar to Cydia splendana.[4]
Biology
The moth flies from April to September depending on the location.[4] They are active in the evening. The larvae feed sometimes on oak (Quercus ilex, Quercus robur),[6] but usually on beech nuts (Fagus sylvatica).[4] The larval stage may last for two years. Pupation usually occurs in a cocoon spun in the soil or in rotten wood.[7] The first adults emerge in late spring.
