Extract

The histological changes in the gut of Chrysops silacea during the digestion of blood are the same as those described by Cragg in Tabanus.

Digestive enzymes are confined to the posterior half of the mid-gut. They comprise an active invertase, a weak amylase and an active tryptase and peptidase. These results are compared with those in Glossina and Calliphora.

The functions of the crop are discussed.
