− | The life-cycle and epidemiology of ''T. tenius'' is very similar to that of the [[Trichostrongylus axei|''Trichostrongylus'']] species of ruminants, and hypobiosis can occur in winter. Eggs are past out in the faeces. The larvae develop in the heather, and are ingested by a host e.g. a grouse, when feeding on the heather. Worms are capable of surviving for up to 2 months, and are capable of causing damage to the intestine and the caecum. | + | The life-cycle and epidemiology of ''T. tenius'' is very similar to that of the [[Trichostrongylus axei|''Trichostrongylus'']] species of ruminants, and hypobiosis can occur in winter.
