Describe the Musca autumnalis life cycle
Typical muscidae life cycle. Eggs develop to larvae (maggots). The larval instars develop to pupae and then to adult flies.
Adult flies feed on face secretions. Female flies lay batches of up to 100 eggs in feces or rotting organic material

animal secretions and wounds
Describe some pathogenesis associated with Musca autumnalis
- annoyance
- transmits viruses, bacteria, helminths, and protozoa

Describe the Stomoxys calcitrans life cycle
Egg -> Larva -> Pupa -> Adult

How long is required for each Stomoxys calcitrans blood meal?
3 minutes
What is/are the site(s) of infection for Stomoxys calcitrans?
general
Where do female Stomoxys calcitrans lay eggs?
