The hairy maggot blow fly, Chrysomya rufifacies (Macquart) is native to Australia but has been spreading to a worldwide distribution and is becoming established in the United States. This paper presents the first documentation of the species in Indiana, specifically Valparaiso, Indiana. The species was found in September 2017 and again in October 2019. Its presence is variable in Northwest Indiana, but seems to be found in the fall when the temperatures are at least 30°C prior to collection.
