Neuroptera

The Neuroptera, also known as lacewings, are an order of insects in Europe with around 400 species, found in gardens, forests, and fields. They range from 5 mm to 50 mm, featuring delicate, net-veined wings held roof-like at rest, and slender bodies with large compound eyes. Key families include: Chrysopidae (Green Lacewings) that are bright green, with golden eyes, predatory on aphids (Chrysoperla carnea); Hemerobiidae (Brown Lacewings) which are dull brown, also predatory (Hemerobius humulinus); Myrmeleontidae (Antlions), whose larvae create pit traps for ants (Euroleon nostras).

Colours are typically green or brown for camouflage. Larvae are voracious predators with sickle-like jaws, while adults may feed on nectar or pollen. Their lifecycle (egg, larval, pupal, adult) spans months, with adults active in warmer months. These insects aid biological pest control.

Previously the order also included the Alderflies, and Snakeflies as well, these families have now been moved to Megaloptera. However, for convenience they are listed under this section too.
