Laphria fernaldi
(Back, 1904)
Laphria fernaldi is a of robber fly in the Asilidae. The Laphria is known for effective mimicry, with members resembling bees in both appearance and to deceive and prey. This species was originally described as Dasyllis fernaldi by Back in 1904 before being transferred to Laphria. Like other robber flies, it is a predatory insect that captures other arthropods in .

Identification
Laphria are distinguished from other mimics such as Mallophora by their thick (Mallophora has thin terminal segments on the antennae). Laphria fernaldi may be separated from by specific morphological features, though detailed diagnostic characters require examination of or authoritative keys. The is noted for having particularly realistic bumble bee mimicry among robber flies.

Habitat
Based on observations of related Laphria , members of this are typically associated with woodland edges and forested areas where they perch on vegetation to hunt. The specific preferences of L. fernaldi are not well documented in available sources.
Diet
Behavior
Like other Laphria , L. fernaldi likely exhibits mimicry , including patterns that resemble bees seeking nectar. This mimicry serves dual purposes: deterring that avoid stinging insects, and allowing the fly to approach prey that mistake it for a harmless . Robber flies in this typically perch on leaves or branches, spot flying prey, and pursue and capture it in flight before returning to a perch to feed.
Ecological Role
As a predatory insect, Laphria fernaldi functions as an in its , contributing to regulation of insect . Its mimicry of bumble bees represents a case of in the context of predator avoidance, and potentially in relation to prey capture.
