Field Digger Wasp - Mellinus arvensis
Field Digger Wasp - Mellinus arvensis


Field digger wasp
The field digger wasp (Mellinus arvensis) is a species in the order hymenopterans (Hymenoptera), the suborder Apocrita, the series Spheciformes, the family Sphecidae, and the genus Mellinus.
The field digger wasp reaches body lengths of 7 - 14 mm. The females, are at least 11 mm in length and are thus significantly larger than the males, whose body length does not exceed 11 mm. The body size is determined primarily by the food supply during the larval period. The male larvae are apparently less dominant than the females when feeding.
The bodies of these insects are black, shiny and oblong. There is a yellow, transverse stripe on the pronotum and the carapace is black without markings. The scutellum bears a yellow patch. The first abdominal segment is stalk-shaped, and the second to fifth segments have a yellow stripe which is non continuous on the fourth segment. The legs are yellow but have a dark base.
The females lay their eggs in soil nests or ground nests. Either a new nest is dug, at an average depth of 30 cm, or the females look for pre-existing nests from other digger wasps. In the latter case they are not able to distinguish between already occupied and unoccupied nests, which often leads to violent clashes between them and the owners of the nest in the entrance area. The female digs a nest at which the excavated sand or clay is piled around the entrance.
The eggs are deposited singly and the larvae feed separately. The females bring around 6 flies for each larva until they pupate.
