Like green lacewings, brown lacewings are predators of aphids as well as other small, soft-bodied arthropods such as mites, mealybugs and caterpillars. The adults and larvae are always predacious and the larvae are sometimes referred to as aphid lions. Review the images for tips on how to identify these predators.

2022年11月28日 · The brown lacewing larvae are known as Hemerobiidae. The name Hemerobiidae encapsulates the entire range of brown lacewings species – all of whom have thin, veiny wings and small, long bodies.

Hemerobiidae is a family of Neuropteran insects commonly known as brown lacewings, comprising about 500 species in 28 genera. Most are yellow to dark brown, but some species are green. They are small; most have forewings 4–10 mm long (some up to 18 mm).

2022年6月24日 · Brown lacewing larvae are approximately 1/3 of an inch or less in length and resemble tiny alligators. Larvae have elongated bodies that taper off towards both ends. They are grayish brown with white spots along the sides of the body. They have distinct black pointy legs and small, sickle-shaped mouthparts (Figure 2). Figure 3.

2016年11月30日 · A silk-spinning gland occupies the larval posterior. Larvae “glue” themselves to the substrate by the tip of the abdomen while molting so they won’t fall during ecdysis. Using their middle and rear pairs of legs, brown lacewings can jump into the air like a grasshopper on their way to becoming airborne. They leap first, and then they flap.

2024年11月29日 · Larvae do not carry debris on their backs. They overwinter as larva, pupa, or adult stages depending on the species. The number of generations per year also depends on the species and climate. (8) The larvae hunt on lichen-coated tree trunks or on bare branches.

2015年7月30日 · Larvae and adults feed on aphids, caterpillars, beetle larvae and insect eggs. Print a PDF of this page: Brown lacewing. Back to IPM scouting in woody landscape plants.

All brown lacewings are voracious predators as both larvae and adults. Prey includes tree-dwelling insects such as aphids, adelgids and other small soft-bodied insects. H. stigma is often found in association with the balsam twig aphid (Mindarus …

Larvae of brown and green lacewings are distinguished by an appendage (empodium) between the pair of tarsal claws on the end of feet. Unlike green lacewings, brown lacewing larvae appear to have a prominent neck because the first abdominal segment (prothorax) is elongated in comparison with the second and third segments with legs.

Brown lacewings are less common than green lacewings. The life cycle of brown lacewings requires between 37 to 60 days. Adult female brown lacewings begin to lay eggs after a three to seven day preoviposition period. Females deposit from 100 to 460 eggs. There are one to five generations of brown lacewings per year.
