'''Life cycle'''
+
==Identification==
*Eggs laid in wounds or body cavities
+
''C. bezziana'' is a blue/green fly, with 4 longitudinal black stripes, and around 8-10mm in length.  They are similar to [[Calliphoridae|''Calliphora spp.'']]
   −
*Larvae feed as colonies
+
==Life Cycle==
 +
''C. bezziana'' is an obligate agent of myiasis.  The female lays eggs in fresh open wounds or body orifices.  Eggs then hatch and the larvae begin to penetrate the skin. The larvae then mature and begin to pupate, before becoming fully reproductive adults.
   −
*Larvae drop to the ground to pupate
+
The complete life cycle from egg to adult is 2-3 weeks.
