Berothidae
Berothidae
Common Name
Beaded Lacewings
Overview
Berothidae is a family of small to medium-sized insects within the order Neuroptera. They are commonly known as beaded lacewings due to the beaded appearance of their antennae and wings. They are closely related to other lacewings and owlflies.
Taxonomy
Key Characteristics
- Antennae: Characteristically long and beaded.
- Wings: Membranous with a network of veins, often held tent-like over the body.
- Body Size: Generally ranges from 5 to 15 mm in length.
- Coloration: Typically brown or grey, often with semi-translucent wings.
Life Cycle
- Egg: Laid singly or in small clusters on or near a host.
- Larva: Predatory, often found in termite nests where they feed on termite eggs and larvae.
- Pupa: Enclosed in a silken cocoon, metamorphosing into an adult.
- Adult: Lives for only a few weeks, primarily to reproduce.
Behavior and Ecology
- Feeding: Larvae are predatory while adults generally do not feed.
- Habitat: Often found in wooded or forest areas where termite nests are prevalent.
- Activity: Nocturnal, with adults being more active during twilight or night.
Notable Species
- Spilosmylus apertus: Known for its highly specialized larval forms that prey on termites.
- Nosybus petitionaceus: Features uniquely patterned wings.
Conservation
Berothidae are not widely studied for conservation status, but habitat preservation is essential due to their specific ecological niche involving termite colonies.
Significance to Humans
Beaded lacewing larvae can be beneficial in controlling termite populations, making them of interest for natural pest management.
Fun Facts
- Berothidae larvae have a flat, elongated body shape which helps them navigate through termite galleries.
- The family name "Berothidae" is derived from the Greek word "berotha," meaning delicate.
- Some species possess glands that emit a defensive secretion to deter predators.
- Adults are often mistaken for moths due to their wing shape and nocturnal habits.
