satellite flies, root-maggot flies
Species Guides
5Leucophora is a of kleptoparasitic flies in the Anthomyiidae, comprising approximately 60 described with worldwide distribution except Oceania. Species are commonly known as 'satellite flies' due to their habit of hovering near nests. The genus is associated with bees and solitary , with females shadowing hosts to locate nest entrances for oviposition. Larvae are parasitic on host . Several species are notoriously difficult to distinguish based on external alone.

Identification
External is highly conserved across , making visual identification difficult; male and female genital structures provide crucial diagnostic characters for species-level determination. Some species, such as Leucophora obtusa, are distinguished by unusually dense long erect hairs on abdominal sternites and scutellum margins compared to .

Habitat
Found in proximity to nests of bees and ; collected from deciduous woodland environments where solitary bees nest.
Distribution
Worldwide distribution except Oceania; recorded from Japan, Europe, North America, and South America (16 recognized from Argentina alone).
Host Associations
Life Cycle
Larvae develop as within . Females oviposit in the tumulus at nest entrances of host bees.
Behavior
females exhibit 'satellite' : hovering or 'orbiting' around nests, and actively shadowing host bees back to their burrows to locate nest entrances for -laying.
Ecological Role
of solitary and larvae; regulator of .

Taxonomic difficulty
The exhibits remarkable external morphological uniformity, leading to frequent misidentification. Reliable determination requires examination of male and female genital structures. The distiphallus and ovipositor terminal segments show species-specific modifications.
