Firefly

5798  Hello I am from winnipeg Manitoba, it is September 15th and in the 20s for out door temperature. I found this bug climbing down my wall in my house, I am going through bed bug treatments and was last sprayed September 13th. I am hoping that what ever this bug is, that it is the only one in my unit. I have attached a photo of his back and underside, please help me identify this gross bug.   When it is on its back it flips it’s self over using its butt, a cone shipped thing that comes out from its underwhelming then retracts back when it is on its feet. Eww

This is a firefly (Coleoptera: Lampyridae); likely in the genus Ellychnia, see http://tinyurl.com/hytxztd for an example. Unlike most other fireflies, ones in this genus tend to be active during the daytime rather than in the evening. Ed Saugstad, retired entomologist; Sinks Grove, WV.
