Here is some great information from The Pollinator Partnership on reducing light usage to help our nocturnal pollinators. FYI: It helps Fireflies too!It's #MothWeek and we're sharing ways you can reduce hard to your local moth populations! Artificial light at night (ALAN) disrupts moths in profound ways. Moths have evolved over millions of years to use celestial light cues from the moon and stars to orient their movement💡Turn off unnecessary outdoor lights, especially during spring and summer when moths are most active🏃♀️Use motion sensors and timers to minimize light exposure☀Choose warm-colored bulbs (2700K or lower) over cool white LEDs🌼Create a moon garden with native, pale-colored, fragrant flowers that bloom at night🗣Speak up at neighborhood meetings or with your HOA to promote pollinator-friendly lighting guidelines⚗Avoid pesticides and bug zappers🔗Learn more and download this resource at pollinator.org/blog/lepidoptera See less

Our naturalists have engaged with folks regarding little blue butterflies that they may either see in our park or their yard. They are often mistaken for Karner Blue butterflies which are a classified as a federally endangered species that also happen to live in Wisconsin. They primarily inhabit open pine-oak barrens, oak savannas, and sand prairies that support wild lupine—the sole food source for Karner blue caterpillars which means that it is extremely unlikely that they would be found in Southeastern Wisconsin. So, let us break down what you could be seeing. If you observe the butterfly in photo 1, you will notice that there are no orange markings or tails located on the hind wing. Depending on the season this could be a Spring Azure or Summer Azure or simply known as the Azure Complex. Yes, we know, it is a bit confusing. In photo number 2, you will notice a butterfly with a couple of orange markings on the hind wing as well as tails. This butterfly is known as an Eastern Tailed-blue.Both of the Azures and the Eastern Tailed-blue butterflies are a bluish-grey color and if you see a light blue-grey butterfly it will be one of these species.For comparison, the Karner Blue is also a bluish grey with no tails and lots of orange markings along the hind wing as well as on the upper wing. All the photos were taken by one of our naturalists and the photo of the Karner Blue was taken at Sandhill State Wildlife Preserve in Babcock, WI. The image features three distinct types of butterflies displayed side by side. Each butterfly is positioned against a natural green background, with the leftmost example being the Azure Complex, which has a pale blue color with no orange markings and lacks tails. The middle butterfly, labeled as the Eastern Tailed-Blue, shows a hint of orange along the wing edges and has short tails. The rightmost butterfly is identified as the Karner Blue, which is marked by prominent orange spots on the wings but, similar to the others, does not have tails. The butterflies are perched on various plant materials, with the Eastern Tailed-Blue on a cluster of small white flowers.
