*Bursate
 
*Most members of this superfamily look like short lengths of cotton (typically 0.5-2cm)
 
*The spicules of each species have a characteristic shape
 
*The heads have no distinct features
 
 
== General Life-Cycle ==
 
*The egg is approximately 80µm long, oval, thin-shelled, contains 4-16cells (i.e. it is a typical strongyle egg)
 
*Egg → L1 → L2 → L3 (this occurs on the ground)
 
*L1 and L2 feed on bacteria
 
*L3 is the infective stage
 
*L3 is ensheathed (i.e. the L2 cuticle is retained after moulting as an "outer skin")
 
*L3 cannot feed, but contains a finite amount of stored food to provide energy for movement
 
*Infection is by ingestion of the L3
 
*L3 → L4 → adult (this occurs in the stomach or small intestine)
 
*Parasitic development initially occurs in gastric glands or intestinal crypts (depending on species)
 
*Adults are situated on the mucosal surface
 
*The prepatent period is typically about 3 weeks
