Mayfly: Our Annual Fundraising Event

Join us for Mayfly, an evening to remember!

This year's Mayfly event will take place on Saturday, June 2, 2018  

Mayfly welcomes members of our community, like you, to come together supporting our mission of educating and inspiring children and adults to discover, understand, and respect their natural environment. Last year, thanks in large part to funds raised at Mayfly, we served over 60,000 people through our on-site and off-site programs and reached students and families in Washtenaw, Monroe, Lenawee, Macomb, Oakland, Wayne, Ingham, Jackson, and Livingston counties in Southeastern Michigan.

Join us for this upscale evening to savor delicious food, drinks, and the wonderful evening air in our beautiful outdoor setting. Hear personal stories reflecting the impact of our work, and enjoy an opportunity to connect with like-minded community members.

Online registration for the event is now closed.  Please contact our Main Office at 734-997-1553, or info@lesliesnc.org with any questions.

If you cannot attend Mayfly, please consider making a donation in lieu of attending.

Silent Auction
We have an array of wonderful and unique local items for our silent auction!
Did you know? In 2016, Mayfly was piloted as a Zero Waste event with the help of Recycle Ann Arbor, Angel Food Catering, and Leslie Science & Nature Center staff. The event was a Zero Waste success with 97% of the event waste being diverted from the landfill. Only 1.8 lbs of trash was created for the entire event! We take the commitment of Zero Waste practices, resource management, and landfill diversion seriously, which is why MayFly will again be Zero Waste this year.

Thank you to our 2018 Corporate Sponsors:
