In a life of uncertainties, it's nice to know that we can always rely on nature to bring some peace, calm, and beauty. Every year in New Hampshire we can rely on spring to bring us out of winter, even if that spring takes a while to arrive. One of the other benefits of springtime in New Hampshire is the beautiful Monarch butterfly migration that makes its way through the state. Each year these beautiful butterflies head north and then south again. They're fairly easy to spot, you just need to know when to look. So, when do monarch butterflies migrate through New Hampshire? We'll let you know exactly when to see Monarch butterflies in New Hampshire.
The Monarch butterfly might seem delicate, but did you know they undertake a 3,000-mile migration two times each year?
Every spring the Monarch butterfly makes its way from warm climates like Mexico and Florida towards cooler places up north.
While they’re strong, it’s unlikely that the ones who leave for the journey will make it all the way to their destination. In actuality, there’s a first generation of butterflies who lay eggs along the way. These eggs hatch and continue the trip.
This cycle repeats and these second or third-generation Monarchs are the ones that complete the entire journey. These are the Monarchs we may see in New England. From here, they’ll continue until they get to their northern destination. They’ll stay here until the fall when they head back down south. This is referred to as "overwintering."
Seeing the butterflies is a good indication that summer is nearly here!
While It’s hard to say why the Monarchs make this journey, scientists believe that sensing longer days and warmer weather triggers their flight.
And, when the weather changes again in the fall, back down they go following similar paths!
The best thing about this beautiful migration is that you don’t need to spend any money to enjoy it! Just make sure you’re spending a little more time outdoors this spring.
In fact, if you're asked by a curious spring vacationer, "Are there monarch butterflies in New Hampshire yet?" simply direct them outside.
While the spring and fall migrations are similar, there is one clear difference you’ll see. In the spring and fall migration, the butterflies interact differently. In the spring they’re likely to be solo, but the colder temperatures in the fall cause them to gather in roosts to stay warm.
The route changes slightly each year, but if you want to track the best time to see monarch butterflies in New Hampshire consider checking out last year's interactive map.
