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

I’m hoping with the pictures I’m attaching, we can get the species figured out!

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.

Hello!
I live in Charleston, SC and just today have seen many black flying bugs (1/2 inch long) with orange bellies all around town…literally everywhere I go.

Hi Evan,
This appears to be a March Fly in the family Bibionidae, but there is not enough detail in your images to provide a more specific identification.  See BugGuide for more information on the family.

That’s what I thought too (“love bug” but they don’t have the orange behind their heads. Perhaps just a different type.
Thanks Daniel!

Lovebugs, which generally live further South, are one type of March Fly.
