Myiasis caused by endemic Cuterebra species in the US and Canada is rare, with approximately 60 cases reported in the past 70 years [1]. Most Cuterebra infections manifest as furuncular myiasis with second instar larvae [1] or respiratory infection from mature third-instar larvae [2].

How long does a botfly take to hatch?

Incubation time within the host is anywhere from 5 to 12 weeks. After the conclusion of the third instar, the larvae will emerge from the host, drop to the ground, and begin pupa formation. Under warm and human conditions, an adult botfly will emerge after 2 weeks and have a life expectancy of 9 to 12 days.
