Habitats and Life History
Habitats: According to Shelley (1981): Like most montane species of Sigmoria, truncata inhabits cool, moist rhododendron coves or similar habitats along stream bottoms. However, it seems to occupy a slightly different microhabitat in these environments in that it can live in rhododendron litter as well as that of associated hardwood species. In Yancey County (NCSM A 1993) I collected it in loose piles of leaves in a dense rhododendron thicket.
