| | | Sepsis violacea | | Sepsis violacea belong to the genus Sepsis in the order two-winged flies (Diptera), the suborder flies (Brachycera), the infraorder Muscomorpha (section: Schizophora, subsection: Acalyptratae), the superfamily Sciomyzoidea, the family black scavenger flies (Sepsidae), the subfamily Sepsinae and the tribe Sepsini. This species is commonly encountered throughout the world. It is ecologically associated with humans. | | |
| | | | Adult Sepsis violacea reach body lengths of 3- 4.5 mm and are therefore relatively small. Their sleek, sturdy bodies are dark with a metallic shine. They are more or less hairy. They always have h one or more hair bristle along the anterior respiratory opening (spiracle), just below and above the halteres. Their spherical heads also have bristles. Their antennae have two to three segments. | | |
| | | | The abdomen is wasp-like at the front like an ants. The rear end is often peaked. The wings move up and down almost constantly. They are transparent but have a dark patch close to the outer edges. Their legs are partially covered with bristles. Due to their appearance Sepsis violacea can be easily confused with other species of Sepsidae. | | |
| | | | Sepsis violacea prefer habitats such as deciduous forests, grasslands, dunes and water banks. It is very common in pastoral areas. The adults are active from February to October, and can very often be found on the plants Stellaria holostea and Tanacetum vulgare, whose nectar they live off. They can also be found on feces, which they land on not only to lay eggs, but also to eat (proteins, minerals). | | |
| | | The females lay their eggs directly on the excrement, or more rarely on decaying plant parts, where the substrate serves as a nutrient medium for the larvae who hatch one to two days later. The larvae go through 3 stages of development before they pupate. Pupation takes place in the nutrient medium or in the underlying soil. The pupae have a reddish surface. 14-32 days after the eggs are laid, the adult flies of the new generation leave their pupae.
Sepsis violacea are of ecological importance as they clean the soil. | | |
