Lovebugs

Lovebugs

Dear Mario,
These are neither ants nor bees, but rather, they are flies.  More specifically, they are March Flies and we believe they are in the genus
Plecia whose members are commonly called Lovebugs because they appear in large swarms that contain numerous mating pairs.  More on Lovebugs can be found on BugGuide and on University of Florida Entomology site.

Male March Fly

Male Fall March Fly

Dear Paula,
This is a male Fall March Fly, probably
Bibio longipes based on this description on BugGuide:  “Males are all black with swollen hind tarsi and are hard to distinguish from Bibio slossonae, the other common fall-flying species.”  BugGuide also notes:  “Large swarms consisting of males are common in the fall.”

On Sept 27, 2015, I photographed these two enjoying the after sun on my car door in Catskill, NY. They seemed to be enjoying themselves and so was I! Love to know what they are.
Thanks!

Mating March Flies

Mating March Flies

Dear Ken,
These are mating March Flies in the family Bibionidae, and they exhibit sexual dimorphism in that the head of the male is larger to accommodate the larger eyes.  We believe we have correctly identified your March Flies as
Penthetria heteroptera thanks to images posted to BugGuide where it indicates they are active in the fall, distinguishing them from most March Flies that appear in the spring.

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).”

Male March Fly

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.
