Polideini

Belongs within: Tachininae.

The Polideini are a group of tachinid flies known to attack a wide range of hosts, including caterpillars, scorpions, spiders, centipedes, cockroaches, earwigs and webspinners. Embryonated eggs are deposited in locations where hosts are likely to pass; the hatching larvae are heavily sclerotised to resist desiccation and wait for an opportunity to attach themselves to a host (Wood & Zumbado 2010).

Characters (from Wood & Zumbado 2010): Anepimeral bristle very large, extending posteriorly beyond middle of lower calypter; metathoracic spiracle with almost equal outgrowths of hairs (lappets) along each side of opening, with V-shaped opening between them; syntergosternite 7+8 of male characteristically enlarged, bulbous and shiny, wider than hypandrium.
