A week ago was the first night I noticed sparklers in the air this year. Anticipate them with excitement and joy. There are unanswered questions about the lives of those that surround us.

I grew up with yellow/orange sparklers flying in eastern Michigan. Here I encounter green sparklers. Perhaps you know what I am writing about. Did you grow up with yellow or green fireflies? “Sparklers” or fireflies are names of convenience. It is more important that our kids, grandkids and future generations experience them. Their populations are in decline worldwide.

I usually do not go outside after dark to sit on the Ody Brook Nature Sanctuary bench in the Big Field. It was a pleasantly warm night with no mosquitoes. Late May and June is usually when I dress appropriately to sit out after dark or find ways to be in areas with few mosquitoes.

As a boy scout summer camp counselor where scouts played Capture the Flag, I was stationed to keep scouts from wandering too far. At ground level, mosquitos swarmed me. I climbed a tree and sat for the hour 20 feet up, where only an occasional mosquito arrived. They remain close to the ground feeding on mice and deer.

Fireflies are like nearly all insects. They are not a pest to humans, plants or animals we use. They even help us. It is unfortunate people kill beneficial insects to eliminate a few we find harmful.

Use strategies to minimize biting insects without killing the great majority of other insects. Last week an article was in the paper promoting a company that will kill insects in your yard with chemicals. That reduces healthy living conditions for mammals, birds, predatory insects, pollinators and humans. Have you wondered why signs are posted “stay off the lawn” after treatment? The chemicals are harmful to people and most life.

Fireflies, bumble bees, soldier beetles, ants, honey bees, butterflies, crane flies, carrion beetles, and other insect species that keep nature niches healthy are killed. It is better to avoid chemicals used to create lawns that are picture-perfect carpets devoid of weeds and insects. There are strategies to comfortably live with insects.

Enjoy exploring your surroundings to discover the lives of close neighbors in your yard. Fireflies are not flies. When we see the word fly connected with a prefix such as Butterfly, fishfly, and dragonfly, realize those are not flies. Things like bee fly, robber fly, and housefly are flies.

Flies comprise one classification Order. Entomologists use classification when working to keep food production, forest protection, and human safety secure. Integrated Pest Management is primary for reducing chemical use. Question companies promoting chemical use. Many use strategies to reduce chemical use. Avoid fertilizers, herbicides, and insecticides and have a more natural yard that supports life instead of reducing it.

Fireflies, also called lightning bugs, are beetles. Realize they are not flies or bugs. Bugs are an Order including stinkbug, milkweed bug, and giant water bug. Lightning bugs flash through the air entertaining us. More importantly, they flash to attract mates for reproduction. Help them by maintaining a healthy environment where they will find chemical free food, water, and shelter in suitable living space. Larvae are carnivorous feeding on smaller insects, snails and slugs. Allow them to eat insects and snails in your garden for free instead of killing them with pesticides. Adults feed sparingly and are short-lived. They mate, lay eggs and die.

Fireflies are declining worldwide so use strategies to help them survive. Avoid use of fertilizers, pesticides and herbicides. Keep lawn mowing infrequent and to minimum size to enjoy the wildflowers that show up in the lawn. Add native trees and shrubs and avoid planting exotic species that few insects can use. Leave some dead leaves and thatch on the ground to hold moisture. A moist habitat is essential for “sparkler’s” survival. Turn off outdoor lights interfering with firefly behavior. You will save energy and money while helping save fireflies.
