When Do The Fireflies Come Out In Michigan?

Fireflies, also known as lightning bugs or fireflies, are a common sight in Michiganders’ backyards during the summer months. They appear in May, June, or July depending on the climate, and are believed to disappear due to human development and light pollution. In West Michigan, fireflies typically appear between mid-May and mid-June. Immature fireflies live underground during winter, mature during spring, and emerge in early summer from the third week in May to the third week in June.

Michigan is experiencing more fireflies than usual this year due to an early spring followed by drought-like conditions. Fireflies often gather closer to water and wooded regions, making it easier for those looking to catch them. A new report by Bridge MI highlights that Michigan’s warm spring weather followed by a dry stretch led to fireflies maturing at an increased speed, resulting in the large numbers of fireflies.

Researchers say that fireflies are disappearing across the country, and they are one of the most underrated hallmarks of the warmer months in Michigan. Fireflies, which are beetles, share a relationship with weather that goes deeper than the summer solstice. Their larvae live underground during winter, mature during spring, and emerge in early summer from the third week in May to the third week in June. The best time to see fireflies is about 10-15 minutes after dusk, so if it gets dark around 9 pm, go outside at about 8: Congaree National Park holds an annual event for visitors to view the fireflies, which blink for a few weeks every May and June.

In summary, fireflies, also known as lightning bugs, are a significant part of the Michigan summer season. They thrive in muggy weather and make an early appearance on lawns when conditions arrive before June.
