One of the most magical parts of a Michigan summer is when the fireflies emerge, putting on a light show in yards, fields and parks.
Fireflies are not actually flies, but beetles that use bioluminescence for attracting mates, warding off predators and signaling danger. Before they enter their bright adult stage, fireflies live under the soil for up to 2 years and feed on snails, slugs and other garden pests.
Firefly populations can be negatively affected by light pollution, habitat loss and pesticide use. To get more fireflies in your own yard, you can incorporate more native plants into your garden, use timer or sensor outdoor lights, and/or discontinue use of insecticides, especially in moist habitats that might be home to firefly larvae.
