Steel are obtained waste from local machining workshops and then various proportions, including 0.25, 0.5, 1.0, 2....

The principal habitats of immature Orthopodomyia alba and Orthopodomyia signifera are tree holes, though they are occasionally encountered in artificial containers. We collected 929 Or. alba and 17 Or. signifera from 2 plastic trash cans, 2 scrap tires, and a tree hole. All collections were made in an urban residential area in central Illinois.
