Lovebug season in Florida, and why days matter
Lovebug remains are acidic, and they etch a finish while they dry rather than after. On a leading edge in Florida in May, the window between a wash and a correction is measured in days, not weeks. That is the whole post, and everything below is why.
We run Orlando, Kissimmee, West Palm Beach, Naples and the rest of the Florida fields, and every May and September we have the same conversation with somebody who is surprised.
Why they are worse than other insects
Two reasons, and they compound.
The remains are acidic and they become more so. As the body decomposes, the fluids become increasingly acidic. That acid sits directly on the topcoat, and on a hot surface the reaction runs faster.
They arrive in volume and at speed. Lovebug flights concentrate at low altitude, which puts them exactly where an aircraft is on departure and arrival. The impact spreads the remains across the surface rather than leaving them as discrete points, so you get a film rather than spots.
Add ramp temperature. A dark leading edge in central Florida in May is well above ambient. The acid is not sitting on a cool surface, it is sitting on a hot one, and the drying that concentrates it is happening fast.
The timeline that actually matters
We are not going to publish a number of hours, because it depends on the aircraft’s color, the surface temperature, the humidity and how much is on there. What is reliably true is the sequence.
Same day. Comes off with a soak and a mild aviation cleaner. Nothing is etched, nothing is corrected, the job is a wash.
A few days. The residue is bonded and needs dwell time and repeated passes. Still a wash, but a longer one, and the surface underneath may show a shadow.
A week or more in heat. Now there is etching in the clear or the topcoat. That is not a cleaning problem any more. Removing an etch mark means removing material around it, which is correction, which spends film thickness you do not get back.
The thing that surprises people is that the aircraft in the third case may not look dramatically worse than the aircraft in the second. The damage is at a scale you see in raking light and not in a hangar.
What to actually do
- Soak, do not scrub. Wet towels laid over the leading edges and the radome, left to sit. The remains need rehydrating before anything touches them. This is dwell time again and it is the entire technique.
- Use a proper aviation cleaner at its correct dilution. Not a stronger one because there is more of it. The dilution is the dilution that was tested.
- Do not use a bug sponge or a mesh pad. The automotive tools for this are abrasive and they are designed for automotive clearcoat, which is not what is on your leading edge.
- Be careful around the radome and the boots. A radome has its own coating considerations and the airframe manual governs. Boots want mild soap and water and nothing else, and solvents attack certain boot materials.
- Watch the windscreen. Acrylic, and the thing people most want to attack with a strong product. Flood it, do not scrub it, and keep glass cleaner off it.
- Rinse thoroughly. Acidic residue left in a seam is not an appearance problem.
The practical version for an operator
During May and September in Florida, the useful intervention is not a better product. It is a shorter gap. An aircraft that gets a leading edge wipe down after each flight during the season will never need a correction for this, and one that gets a thorough wash every three weeks probably will.
This is one of the few genuinely seasonal things we do differently. Through the lovebug flights we run more frequent, lighter touches at Orlando, Kissimmee, West Palm Beach and Naples rather than the same interval and a harder job. It is cheaper for the client and it costs the aircraft nothing.
One thing worth telling your crew
If they land during the season and the aircraft is going to sit, a wet towel over the leading edges before they walk away is worth more than anything anyone does three days later. It takes two minutes and it keeps the problem in the cleaning category.
Protective coatings help, in the sense that they make removal easier and buy a little time. They do not make the remains non-acidic and they are not a substitute for getting them off. We are honest about what a coating does and does not do in is ceramic coating worth it on an aircraft.
If you are based in Florida and you want the season handled rather than reacted to, that is what the exterior service looks like when it is scheduled around what is actually happening outside.
Questions people actually ask
Short answers
Do lovebugs damage aircraft paint?
Yes, if they are left. The remains become increasingly acidic as they decompose, and on a hot leading edge that acid etches the finish while it dries. Removed the same day it is a wash. Left a week in heat it can require correction, which removes topcoat.
When is lovebug season in Florida?
There are two main flights each year, in late spring and again in late summer, typically peaking around May and September. They concentrate at low altitude, which puts them directly in the path of aircraft on departure and arrival.
How do you remove lovebugs from an aircraft?
Soak rather than scrub. Lay wet towels over the leading edges and radome and let the remains rehydrate, then use a proper aviation cleaner at its correct dilution with dwell time. Avoid abrasive bug sponges and mesh pads, be careful around de-ice boots and the radome, and flood the windscreen rather than scrubbing it.
