Laphria sicula

Members of the genus Laphria can be distinguished from similar bumble bee-mimicking robber flies in the genus Mallophora by their thick antennae (Mallophora has a thin terminal segment on the antennae). Laphria species are generally less hairy than Mallophora. Within Laphria, specific identification to species level requires examination of detailed morphological features; L. sicula specifically has not been described in sufficient detail in the provided sources to distinguish it reliably from congeners without reference to original taxonomic literature.

Has been observed exhibiting bumble bee mimicry, a trait common to the genus Laphria. This mimicry involves both visual resemblance and behavioral mimicry, including flight patterns that resemble those of bumble bees rather than the typical erratic flight of most flies. Like other robber flies, it is an aerial predator that captures prey in flight.

As a predatory robber fly, functions as an apex predator among flying insects in its habitat. Contributes to population regulation of other flying insects through predation.

• MallophoraBoth genera are effective bumble bee mimics with similar overall appearance. Distinguished by antennal structure: Laphria has thick antennae throughout, while Mallophora has a thin terminal antennal segment. Mallophora species are also generally hairier than Laphria.
• Microstylum morosumBoth are large robber flies in the family Asilidae, but Microstylum morosum is dramatically larger (35–50 mm vs. typical Laphria size), lacks the bumble bee mimicry, has a streamlined body almost devoid of setae, and possesses large, shimmering emerald eyes. Microstylum morosum is a Great Plains species with different habitat preferences.
