These patterns may be as plain as a series of dashes or dots or more elaborate, such as a swooping "J. Some species are active just before sunset, others just after. Temperature also affects fireflies--as it gets warmer they flash more often and the flash appears brighter. Fireflies overwinter as larvae buried in the soil. The larvae are predaceous and have elongated, sickle-shaped jaws that are used to inject a toxin into their prey.
This toxin also aids in liquefying the prey's body contents so the firefly larvae can suck their victims dry. The larvae feed chiefly on land snails, earthworms, caterpillars, and other soft-bodied invertebrates. They are nocturnal and are found on the ground in moist areas, usually under bark or stones or in decaying vegetation. Firefly blood contains lucibufagins, a defensive steroid that tastes really gross.

When wetlands are lost or become degraded, results can include a higher risk of flooding, wildlife habitat deterioration and water quality decline. Over the years, Lake County officials have identified where high-quality wetlands remain, and are working to restore degraded wetlands and ensure no more acreage is lost. A draft plan has been created to prioritize wetland restoration and preservation efforts.
The plan identifies 15, acres of potentially restorable wetlands. The Lake County Stormwater Management Commission will host a web-based virtual public information meeting on the plan at p. The damper the soil, the more plentiful these creepy-crawlers will be, and the more food young fireflies will have to carry them into adulthood.
As much as damp weather provides an ideal environment for fireflies, dry conditions provide the worst. The dates when lightning bugs appear will also be delayed due to the heat stress. On warm and humid evenings, lightning bugs can light up a field as if it were a Christmas tree!
Why is this? Fireflies, like most insects, are cold-blooded meaning they depend on heat from their surrounding environment to help them function , so their activity peaks when temperatures rise and slows when temperatures drop.

According to people that have lived and grown up here, there used to be fireflies, but significant amounts of pesticides likely wiped out the majority of firefly populations.
I have heard of firefly sightings about 6 miles away, so have been hoping they would find their way to us. Any thoughts? How close is your nearest farming community? We had them here as well in illinois, but this year there was a smaller amount and they have already died off. The culprit is most likely a combination of insecticide and herbicide being sprayed by farmers.
They cropdust here. We are surrounded by farming: used to be mostly cotton, but now primarily soybeans, corn, and rice. I am hopeful that they will make a comeback!
