The larvae have been found in northern California living in tree holes of pine or oak below 600 m elevation and on small rain and snow protected rock shelves at higher elevations. In both habitats they are in fine organic matter with their legs holding onto a solid substrate. Larvae have also been found in houses near the forest. In one case larvae were found living on top of a basement refrigerator covered with dust. Adult females use substrate testing with the end of their abdomen to determine suitability of egg deposition sites before coating eggs with fine material and leaving them on the surface. The females of this species appear to be unique in the family studied so far in that they die shortly after laying their eggs instead of continuing to feed and developing more eggs (Miller 1990).
