Volunteers Needed for Lange's Metalmark Butterfly Surveys!

Lange's Metalmark Butterfly on Buckwheat

It is time once again for the Lange's Metalmark Butterfly counts at Antioch Dunes National Wildlife Refuge. We will be counting butterflies for several weeks in August and September and we can sure use your help. We will be surveying one day per week in August and September. We’ll meet for training on site at 9:15 a.m., then survey until 4 p.m. at the latest, the times in which our butterflies are the most active.  

The dates for the butterfly counts will all be on Thursdays. The weekly count dates will be:
August 3, 10, 17, 24, and 31
September 7, 14 and if they are still active, on 21  

We will be conducting counts until ZERO butterflies are seen, whenever that may be in September. You'll be briefed on what to do and what to look for on each day of the count, so first-timers are welcome as well as veteran counters!

You must be at least 18 years old.

What to Expect
As you might guess, Antioch in summer is challenging. Temperatures can be very warm to hot, often with a nice breeze, and the terrain can be uneven and sometimes steep. There are many plants to step over, under and around, as well as stickery plant parts that will want to go home with you. However, if you are of the hardy variety, the payoff is fabulous and worth it! Lange's metalmark butterflies are found nowhere else in the world, except at the Antioch Dunes National Wildlife Refuge!! Don't miss this opportunity to see this gorgeous endangered species!!!

What to Wear and Bring
Volunteers will need to wear sturdy shoes/boots, long pants like jeans (star thistle smarts!), and bring/wear sun-protection, sunglasses, hat, lunch and WATER BOTTLE!!!  We can provide short gaitors to help keep weeds out of your shoes, but if you have your own long pair, you might want to bring them. They really help keep the weeds out of shoes, socks and laces.
