They are best known as a predator of aphids, and fully deserve the nickname “aphid lion” as a single insect can consume 100-600 aphids in its lifetime. Adults hibernate over winter, and breed in the summer. The first larvae to emerge are brown , about 4mm long, with sharp nipping claws at the front (beware!). The older larvae are paler, about 13mm long, with bristles on their back. Lacewings are supplied as juveniles, or larvae.
This is the most common of our green lacewings and the only one to hibernate. Late in the season it loses the green pigment and becomes straw coloured. It often has a pale strip along its dorsal surface and also has hairy veins on its wings, can just be seen with a hand lens.
There are several other green lacewings so identification normally requires close examination of the specimen.
Various habitats, often entering houses as it prepares for hibernation, and on summer evenings when it is attracted to lights.
When to see it
All year round hibernating in winter with the peak time being May to August.
A predator of aphids.
There isn’t much information for this find. They seem quite rare as you can see by the NBM map below where sighting are recorded
These are small grey-white winged insects related to lacewings. They are often known as waxwing lacewings or dustywing lacewings. The wings have a dusty appearance caused by a white waxy substance which the insect produces itself.
The adults reach 10–12 millimetres (0.39–0.47 in) of length, with a wingspan of 25–30 millimetres (0.98–1.2 in) and are fearsome predators, primarily feeding on aphids, occasionally on flower nectar. They can be encountered from May through August in cool and shady areas, mainly in deciduous woods, woodland edges and shrubs.
