The species in this family are spread by the oral-faecal route.
Development occurs in the epithelial cells of the gut or rarely in the Malpighian tubules.
The gamontocysts are enclosed in a thick gelatinous capsule.
Syzygy and encystment occur in the lumen of the gut (or tubule).
About 25-30 spores are generated from each gametocyst.
