Members of the well-known family Bibionidae, these small black flies with red thoraxes have come to be known generally as "March Flies." They are indigenous, I understand, to the western part of the country; however, somewhere in the 1940s a high-risk-taking gene group broke away from the safety of the family settlement and set out for Florida. Flights have been progressively moving southward in the state and soon, if my experience is any kind of an indicator, will become an as identifying part of Florida as is the seasonal influx of the order human. This latter group might rightly be referred to as "March Flyers."
Pleacia Nearctica Hardy goes by another name in Florida: the "lovebug." The reason for the name will become apparent as you read on. Two flights of these little lovebugs occur each year. The spring flight during late April and May, and a second swarm during late August and September. Flights extend over periods of 4 to 5 weeks. A noteworthy feature of the lovebugs (and hence, their name) is their ability to combine copulation and locomotion in a way that the other "March Flyers" would never be able to pull off. Males are 1/4 inch, and females are 1/3 inch in length. Join the two together, (which is how they fly) and you've got a moving missile nearly 3/4 of an inch coming at you in a state of rapture.
Motorists hate them because they collide with and mess up the inside and outside of vehicles. They get in under the hood through the fender portion of the car, and drivers resort to a preventative netting attached to the fender area to thwart entrance. The lovebugs' connubial carcasses are a threat to the paint job of a vehicle as well.
I could personally give a rat's ass about our car; it's Arthur I'm worried about.
Female lovebugs lay 100 to 350 eggs. They and their mates die after two or three days. Larvae emerge and mature into pupae. The pupae's stage requires about 7 to 10 days. This means that in a week to 10 days, Arthur will boast of having more inside than just Intel. With larvae nestled in his motherboard, pupae in his pentium, and, finally, a zillion post-coitus corpses eating away at his insides, Arthur does not have a good prognosis.
