Myiasis-Causing Flesh Fly

A large flesh fly found in North America that causes obligate dermal myiasis in small animals including rabbits, mink, and fox kits on fur farms. Females deposit active larvae on the unbroken skin of young animals, and larvae burrow into subcutaneous tissue. Human cases are rare but documented in infants.
