==Habitat and behavior==
Like all robber flies, the violet black-legged robber fly feed by perching on lower stems of grasses and attack prey as it flies by. The larvae usually grow up in dung piles or decaying organic matter, but they can also be in regular soil.〔
Courting behavior involves the male leading the courtship dance in front of the female. If she isn't impressed, she'll rapidly move her wings or fly away; otherwise the male will begin copulating.〔Melin, D. (1923): Contribution to the knowledge of the biology, metamorphosis and distribution of the swedish Asilids. – Zoologiska Bidrag fran Uppsala 8: 317 pp.; Uppsala〕
