This is a bug that has 6 legs. It looks like it has a very small abdomen. The bug has been seen in Letterkenny, Co. Donegal, Ireland, including my bedroom window. There is a photo of it I took. I have been mystified by this insect and can’t find it anywhere online.

Male March Fly

Male St. Marks Fly

Dear Justin,
We believe this is a male, because of his big eyes, March Fly in the family Bibionidae.  Your individual looks similar to the image posted on the GoFlyFishingUK site.
  After visiting iSpotNature, we believe this is a St. Marks Fly, Bibio marci.

March Fly

March Fly

Hi Sylvia,
This looks like a March Fly in the family Bibionidae to us, and the large eyes indicate it is a male.  The March Fly family includes the infamous Love Bugs that are found in the south.  According to BugGuide:  “Adults emerge synchronously in huge numbers and often form dense mating aggregations. Males form loose “swarms” and copulate immediately with females as they emerge from the soil. After mating, female bibionines dig a small chamber in the soil with their fossorial fore tibiae, lay eggs, and die within the chamber (Plecia lay eggs on the soil surface). Adults are short-lived (3-7 days).”

We are relatively confident we have correctly identified your male March Fly as Bibio femoratus, based on its resemblance to the individual in this image posted to BugGuide.

I was playing with my son in the yard, when I felt something crawling on my leg. I let it walk onto my hand, and then I put it on the bush…didn’t want to squash them, while they were mating :-)

March Flies

March Flies

Dear Bob,
These are March Flies in the family Bibionidae, and they are an example of extreme sexual dimorphism.  The male on the left has a large head and eyes, while the head and eyes on the female on the right are much smaller.  According to BugGuide:  “Adults emerge synchronously in huge numbers and often form dense mating aggregations. Males form loose “swarms” and copulate immediately with females as they emerge from the soil. After mating, female bibionines dig a small chamber in the soil with their fossorial fore tibiae, lay eggs, and die within the chamber (Plecia lay eggs on the soil surface). Adults are short-lived (3-7 days).”

Thank you for the quick reply. I appreciate the information, and your response.
Bob

Dear Courtney,
This is a female (small head) March Fly in the family Bibionidae, as you suspect.  We are not certain of the species.

March Flies

Dear Concerned home owner,
These are March Flies and we believe we have correctly identified them as
Bibio fraternus thanks to images posted to BugGuide.  Many March Flies are sexually dimorphic, with males having bigger heads and huge eyes and females having much smaller heads and eyes.  We do not provide extermination advice.
