Found this bug on the front of my house under the garage light. Has been there for 3 or 4 days now and has only moved a couple of inches that I know of. You can estimate it’s size from the standard house brick it is sitting on. Did not want to bother it until I knew what it was or may be doing. Thank you for your help in the past and I hope you had a great Easter.

Dear Dan,
This sure looks like a female Spring Fishfly,
Chauliodes rastricornis, to us.  According to BugGuide:  “The antennae of females are almost linear, with just a little jagginess on the edges, i.e., serrate (saw-like)” and “Adults typically fly late spring: March?-May (North Carolina), April-May (West Virginia). Seen into early June in New England (Massachusetts–guide photo). Further south, much of year (Florida).”
