Laphria semitecta
(Coquillett, 1910)
Laphria semitecta is a of robber fly in the Asilidae, described by Coquillett in 1910. It belongs to the Laphria, a group known for effective mimicry. The species is part of the diverse North American robber fly fauna, though specific documentation of this species in the provided sources is limited. Robber flies in this genus are predatory and often visually striking due to their mimicry adaptations.

Identification
Laphria are distinguished from other -mimicking robber flies by their thick, clubbed (in contrast to Mallophora, which has a thin terminal antennal segment and hairier body). Laphria semitecta specifically would require examination of or detailed original description for definitive identification beyond -level characters. The genus is characterized by robust, -like flies with dense pile and often banded abdominal coloration.
Diet
As with all robber flies (Asilidae), Laphria semitecta is predatory. Members of the Laphria have been observed capturing various flying insects, though specific prey records for L. semitecta are not documented in the provided sources.
Behavior
Laphria are known for their mimicry, which likely provides protection from . They are active hunters that perch and pursue prey in . The specific behavioral repertoire of L. semitecta has not been separately documented.
Ecological Role
As a predatory robber fly, Laphria semitecta functions as an aerial in its , contributing to regulation of flying insect . Its mimicry of bumble bees may also influence dynamics through predator avoidance associations.
Human Relevance
Laphria , including L. semitecta, are of interest to entomologists and naturalists due to their impressive mimicry and predatory habits. They are occasionally mistaken for bumble bees by observers, which can lead to confusion about local diversity.

Taxonomic note
The provided sources contain extensive information on Microstylum morosum (North America's largest robber fly) and general comments about Laphria as mimics, but do not contain specific detailed records for Laphria semitecta beyond its taxonomic placement. Information in this record is derived from -level characteristics where -specific documentation is absent.
