- Genus: Astochia
Visual Description
Members of the genus Astochia are robber flies (family Asilidae) that exhibit typical asilid morphology. Based on observations from the TreeOfLife-200M dataset, these flies possess a slender, elongated body form characteristic of many members of the family.[1] They feature prominent, compound eyes and a robust, piercing-sucking proboscis adapted for predation. The legs are generally long and often equipped with bristles, which aid in capturing and handling prey. The wings are typically clear or slightly tinted, with venation patterns consistent with the Asilidae.[1]
Ecology and Behavior
Research on East Asian robber flies has provided insights into the ecological habits of Astochia. Field observations indicate that species within this genus, such as Astochia philus and Astochia fallaciosus, utilize specific perching sites within their habitats.[2]
- Astochia philus has been observed in coastal forests, where individuals perch on bare twigs. These flies exhibit site fidelity, returning to the same perching location, particularly during morning hours when the site is exposed to direct sunlight.
- Astochia fallaciosus has been noted in coastal forest environments, where it perches on herbs and twigs within the herbal stratum.
The selection of distinct perching sites is considered a behavioral mechanism that helps reduce food competition among sympatric asilid species in these environments.
