Pink-edged Suphur

Pink-edged Sulphur

Sulphurs are medium sized yellow butterflies in the Pieridae family. They have six fully developed legs, unlike the member of the brushfoot family. They can usually be found taking nectar from wild flowers or perched on moist soil, almost always perched with wings closed. Most over winter as a caterpillar pupating in the spring.

We have five sulphurs that are found in this area. This one is a pink-sided sulphur. Many different sulphurs have a pink edge on their wings that some people associate with the pink-sided but the true way to determine if a sulphur is a pink-sided instead of a clouded or orange sulphur is by the number of spots on the hind wing. Pink-sided sulphurs have a single spot on their hind wing compared to two spots on both the clouded and orange sulphurs. Another clue to help determine the type of sulphur is to look in the habitat for the Caterpillar host plant. Pink-sided sulphur caterpillars only eat blue-berry leaves, so the butterflies are usually found in areas near blueberry. Most other sulphur butterfly caterpillars in this area eat legumes, or members of the pea family.

The pink-edged sulphur is one of the members of the sulphur family of butterflies that we can find in my neck of the woods. They look very similar to the other two varieties of sulphurs that are found in the area, especially the clouded sulphur.

From above the pink-edged and clouded sulphurs can easily be mistaken for one and other, especially the males. Both have yellow wings with a black marginal band. On the underside, which is typically how you view sulphurs, both have wings that are lined with pink but the the pink-edged sulphur only has a single central spot on the underside of the hindwing while the clouded usually has two central spots. The third type, the orange sulphur also has a double central spot on the underside of the hindwing and both wings are orange-yellow in color. I photographed this sulphur at Necedah NWR in Wisconsin in June of 2009.

Crex Meadows Road Trip

The second road trip that I took with the new car was to Crex Meadows. Crex is located about 90 miles north of the Twin Cities just over the border in Wisconsin. All together I ended up driving about 200 miles, this included driving around the park and ended up using a little bit over 4 gallons of gas.

While driving I try and keep an eye on the road, an eye on the dash, it turns green when I am driving more efficiently, and an eye out for wildlife. It's a good thing that I have four eyes that way I can also keep one closed to get some rest while I drive LOL. You never know what you might see while you drive like an American kestrel hanging out on the power lines. Fortunately I spotted this kestrel after I left the interstate so I could stop to take some pics. Usually kestrels are quick to fly away when you pull your car over but this little guy did not seem to mind me very much. If you look closely you can see that he has one foot tucked which is not something a bird will do if he is nervous or frightened.

Crex is named for the Crex Carpet Company which owned the land in the early 1900's. The Crex Carpet Co. harvested wiregrass from the areas marsh lands to create grass rugs. In 1933 the carpet company went bankrupt, later, in 1946, the state of Wisconsin bought the land and turned it into the Wildlife Management Area that it is today. The carpet camps are long gone but the marshes where the grasses where harvested from still exist and are now home to a lot of wildlife. One of the most noticeable wildlife that you can often find in the marshes of Crex during the warm months are the very large sandhill cranes. Sandhills can be found in Crex through out the spring and summer but the largest populations are seen in the fall when migrant birds use crex as a staging area for the fall migration.

Crex Meadows stands on what is sometimes referred to as the Northwest Wisconsin Pine Barrens. The barrens is a long narrow sand plain that was formed as the Wisconsin glacier retreated 10,000 to 15,000 years ago. As the glacier retreated north, glacial till was deposited in the area forming the sand prairies that make up the Barrens and much of Crex.

The sand prairies support the growth of many different prairie grasses and plants. Wild flowers like butterfly weed, black-eyed Susan, and blazing star help to add color to the prairie and attract butterflies like the pink edged sulphur, pictured above, and the Aphrodite fritillary, pictured above the sulphur.

As the Wisconsin Glacier receded it also created Glacial Lake Grantsburg over where Crex now stands. Over the years the lake drained away leaving shallow sedge marshes behind. Today there is approximately 6000 acres of open water with in the Wildlife Management Area. Most of this comes from the twenty-nine flowages which are managed by a series of dikes, pumps and transfer ditches. Besides the flowages there are also four natural lakes, numerous ponds and three streams which begin on the property.

These waterways are home to many different types of wildlife including fish, reptiles, mammals, and waterfowl. Some of the waterfowl are visitors who stop in the spring and the fall during migration to rest and to feed. Other waterfowl like the common loon and pied-billed grebe can be found all summer long. The common loon in the photo above is an immature that was born in the park and photographed on Phantom Lake. For more information about Crex Meadows check out their website here.
