Introduction
The soldier fly is a common and widespread fly of the family Stratiomyidae, whose larvae are commonly found in compost heaps. Larvae of the soldier fly are beneficial in that they prevent houseflies and blowflies from laying eggs in the material inhabited by the soldier fly larvae. They are usually not a pest as they are not attracted to human habitation or foods, they are very easy to catch and relocate when they get inside a house, they are sanitary, and they do not bite or sting.
The female of this species of soldier fly, Boreoides subulatus, is often referred to as a “walk”, due to its lack of wings. The adult males do have wings but they are much smaller than the females.
Identification
- Soldier flies from this subfamily have robust bodies with short antennae.
- Grey or brown colour, can have red heads.

Female wingless soldier flies are often encountered on walls and fences, .
Life history cycle
- The larva start their lives in compost and soil, moulting uptp six times before emerging as adults when autumn rains come.
- The female adults climb tree-trunks, walls and fences, where they are found by the smaller winged males.
- The female then lays masses of long white eggs on the fence, wall or tree trunk.
