Myathropa

Myathropa is a genus of hoverflies (family Syrphidae). These flies are characterized by their striking wasp-like appearance, a form of mimicry believed to deter predators. They are found throughout Europe, Asia, and North America.

Description

Myathropa species typically exhibit black and yellow or orange markings, resembling wasps or hornets. This coloration varies depending on the specific species. They have a distinctive elongated abdomen and, like all hoverflies, possess the ability to hover in mid-air. Larvae are typically saprophagous, feeding on decaying organic matter in wet environments such as tree holes and ponds.

Distribution and Habitat

Myathropa flies inhabit a variety of environments, including woodlands, meadows, and gardens. Their distribution spans across the Holarctic region, encompassing Europe, Asia, and North America. They are often found near water sources due to the larval habitat preferences.

Ecology

Adult Myathropa flies are important pollinators, feeding on nectar and pollen from a variety of flowering plants. Their larvae play a role in decomposition and nutrient cycling within aquatic and semi-aquatic habitats. The mimicry of wasps provides a defensive advantage against predators.

Species

Several species are recognized within the genus Myathropa, including but not limited to:

• Myathropa florea (Linnaeus, 1758) - Commonly known as the dead head hoverfly.

Taxonomy

Myathropa belongs to the subfamily Eristalinae within the family Syrphidae. The classification of hoverflies and their relationships is an area of ongoing research, and taxonomic revisions may occur.
