This is an excellent message from Prairie Moon Nursery in Winona, MN with common sense suggestions for helping Fireflies (or Lightning Bugs):
“Whether you call them fireflies or lightning bugs,
over 150 different species of these mystical beetles make their home in North America - and every single one of them is declining.
Things you can do to assist these whimsical creatures:
1. Create a Space – Fireflies thrive in secluded, moist, organically rich environments. Set aside a portion of your land for a little bit of wilderness; allow a diverse mixture of native grasses and flowers to grow taller than the manicured lawn. Most female fireflies send their signals from perches, blinking like little lighthouse beacons.
2. Don't Use Insecticides – need we say more?
3. Turn Off the Lights – light pollution is easy to fix and instantly reversible. Keep outdoor lights to a minimum to allow lightning bugs optimal communications with each other. No love language? No new lightning bugs.
(Sallie’s Note: I learned from entomologist, Douglas Tellamy that if you leave outdoor security lights on all night, insects cannot communicate. Realistically, we homeowners are seeing an increasing need for outdoor security lights as crime rates rise. Please consider this option: change your “all night long” security light to a motion detector light. )
4. Talk to the Neighbors – the efforts you make on your property are important - but fireflies are not limited to a single plot. Together, we can bring these nostalgic little beetles back from the brink and enjoy their dazzling performances again!
Native plants are key in providing habitat as well as nectar and pollen for adult fireflies. They also enrich the soil with leaf litter, inviting the soft-bodied insects that firefly larvae feed on.
