HOUMA — This year’s hot and humid weather could make this one of the worst lovebug seasons in south Louisiana, bug experts said.

Lovebugs, so called because of their tendency to fly attached to one another while mating, are a problem for the exteriors of vehicles and structures, LSU AgCenter agent Barton Joffrion told The Courier.

The insects’ scientific name is Plecia nearctica, but they’re also called march flies, lovebugs and united bugs.

“Now’s the time for them to really start, and in the last two or three days, they’ve really started to show up,” Joffrion said
