Oct to April- Spring generation
May to September- Fall generation
Lovebug larvae are beneficial
Recycle decaying organic matter
Large numbers found under cow manure Did You Know ?
15. Female lovebugs larger than males
Deposit ca. 350 eggs
Adult lovebugs live only 3- 4 days
Lovebugs separate on vegetation but not in flight or at night
Male lovebug’s eyes 4X larger than the female’s
Help locate potential mates

Larger males near bottom of swarms have greater mating success
Up to 8 males compete for 1 female
Mating lasts up ca. 56 hrs
(or until smashed by a vehicle)
17. Several factors contribute to the lovebug problem
Improved pastures (thatch) & cattle production (manure)
Reduction in annual burning of woodlands and leaf litter
Banning of DDT for insect control in mid-1960s
18. Lovebug mating flights:
Occur Apr-May & Aug-Sept
Reach altitudes of 1500 ft
Extend several miles over the Gulf of Mexico
Cover 25% of Florida’s land area
Occur between 10 AM & 4 PM at a temperature above 82 oF

20. Lovebugs congregate at highway intersections, traffic lights, filling stations, and truck stops
Are attracted to exhaust fumes (formaldehyde), hot engines, and vehicle vibrations
21. Lovebugs have natural enemies

Spiders eat adults
Humans (vehicles kill adults)
Lovebugs are economically important
