Invertebrates of Whitefish Dunes State Park

Whitefish Dunes is home to many kinds of animals without backbones--insects, spiders, crayfish, worms, and more. We can't begin to list all of them, but here are some clues to help locate some of the common and more interesting ones.

• Ant lions [exit DNR] make their traps in the sand.
• Butterflies are prevalent on sunny days after the heat has warmed their bodies.
• Moths [exit DNR] are most likely to be found near lights at night.
• Beautiful spider webs in many varieties becomes visible the morning after heavy dew (though always there, they often go unnoticed).
• Dragonflies and damselflies abound near a wetland where much of their life cycle occurs.
• Crayfish hide under rocks in the water.
• Sowbugs and centipedes hide under rotting logs.
• To locate a particular insect or caterpillar, first find its favorite food plant.

• Sounds are helpful, whether it be the familiar sound of a cricket or the resounding buzz of the cicada song on a hot summer day.

By closer observation you will find that these creatures are fascinating and beautiful to observe and are very important members of our world.
