As we enter early July and the heart of the summer season, the restored prairies in our Fox River watershed are ablaze with colorful flowering plants. The Wild Bergamot, Coneflowers of many types, Common Milkweed, Butterfly Weed, and other beautiful plants are near their peak bloom.
The profusion of these beautiful flowers also has led to a large increase in the numbers and types of pollinators doing their vital work to help sustain themselves, the life cycle of the plants they visit, and indeed, all life on our planet.
A Slow Start Begins to Show Promise
I was quite concerned earlier in the summer as I saw very few pollinators (honeybees, native bumble bees, butterflies, and others) when I went on my hikes on the prairies in our local forest preserves. Lately, however, I have seen a big jump in the number of pollinators, particularly bumble bees and butterflies, that I see on my near daily hikes. I’m particularly heartened to see quite a few Monarch butterflies that have been in serious decline in recent years. On a recent hike in the Hoover Forest Preserve near Yorkville, I counted 37 Monarchs! I don’t think I have seen that many in the last two years combined! Before I get too excited about their potential comeback, I know that my local experience is not necessarily representative of the butterfly population overall, but it gives me some hope that they may be starting to recover. Time will tell.

Buzzing Bumble Bees
I’m also starting to see many different native bumble bees (Bombus genus) busy visiting the native blossoms to collect nectar and pollen to ensure their survival and the survival of their young. In the process, the bees provide an essential service to the plants by pollinating them, which enables the plants to produce fertile seeds thereby assisting the plants in sustaining their species. Approximately three-quarters of North American plant species require assistance from an insect, bird, or animal to help them reproduce. NOTE: If you are interested in learning more about the 12 species of bumble bees that are native to Illinois, the Forest Preserve District of Kane County in conjunction with the St. Charles and Geneva Park Districts, is sponsoring a “Learn from the Experts: Bumble Bees of Kane County “ presentation on Saturday, July 19, 2025 from 1 to 3pm at the Creek Bend Nature Center in the Leroy Oaks Forest Preserve. Registration is required. Call 630-444-3190 for more information.

A Mutually Beneficial Relationship Between Pollinators and Plants
This symbiotic relationship between pollinators and plants leads to really beautiful scenes in a restored prairie in the summer. The blossoms of the prairie plants are naturally designed to attract the attention of pollinators through their shapes and colors. These differently shaped and colored flowers are aesthetically pleasing to us human visitors to the prairie too! The pollinators themselves are interesting and beautiful in their own right. For the remainder of my article this month, I’ll show some photographs of the types of flowering prairie plants that I commonly encounter on my hikes and the various species of pollinators that visit them.
Wild Bergamot is near its peak bloom right now (early July) in the prairies of northern Illinois. This is in the Jay Woods Forest Preserve near Plano.
Grey-headed Coneflower is one of the species of coneflowers that is beginning to bloom quite profusely on local prairies.
A Butterfly Weed (a type of native milkweed) blooms on the prairie in the Jay Woods Forest Preserve near Plano.
Purple Coneflower plants are blooming now in the Hoover Forest Preserve. They are really beautiful!
Black-eyed Susan adds yellow and sometimes varying shades of orange to the color palette of local prairies. They are blooming now too!

Another butterfly that helps to pollinate the native prairie plants in our region is the Great Spangled Fritillary. While considerably smaller than the Monarch and the Swallowtails, they are spectacularly beautiful.

A yellow morph of the Eastern Tiger Swallowtail butterfly visits a Wild Bergamot.
A small native bee (perhaps a type of Nomad bee) visits the blossom of a Philadelphia Fleabane plant along the trail in the Hoover Forest Preserve. There are many, many species of native bees that pollinate the plants of our watershed.
Two small beetles visit the blossom of a Pale Purple Coneflower in the Grasslands of the Fox unit of Silver Springs State Park south of Plano.

One of my favorite pollinators to photograph, the Hummingbird Clearwing is a type of moth that closely resembles a hummingbird in the way it flies. Unlike many moths, Clearwings are very active during the day. While not extremely common, they are definitely present in the Fox River watershed.
Another type of Clearwing moth present in our area, the Snoberry Clearwing is slightly smaller that the Hummingbird Clearwing and is primarily black and yellow. They also have black legs whereas the Hummingbird Clearwings have lighter colored legs.
Hummingbirds themselves are important pollinators too! Here, a female Ruby-throated Hummingbird (it could possibly be an immature male too) is pictured visiting some bushes along the Fox River in the Hoover Forest Preserve.
A different type of bumblebee, possibly a Common Eastern Bumblebee, visits Common Milkweed.
Another bumblebee, perhaps a Common Eastern, visits a blooming thistle plant. Here, a ‘basket’ of pollen is visible on one of the bee’s legs!
