Winter Midges!

"February is the uncertain month, neither black nor white but all shades between by turns. Nothing is sure." 

— Gladys Taber
Finally some sunshine! 

A winter expedition at Pheasant Branch unveiled a serene yet dynamic landscape. The persistent cloud cover for the past few weeks seemed momentarily forgotten as a burst of sunshine broke through, casting a natural spotlight on the frozen surroundings. The recent thaw revealed large areas of grassland, once concealed by the deep snow, creating a striking contrast against the lingering white blanket that still covered many parts of the prairie. This thaw-and-freeze dance had shaped the landscape, turning the hike into a journey through gorgeous contrasts.
The birding scene was minimalistic but delightful, featuring a single Troglodytes hiemalis, a lone Falco columbarius, and just one Certhia americana. These singular sightings emphasized the quiet beauty of the winter landscape, where each bird plays a unique role in the hushed tableau of Pheasant Branch. Having said that, there were dozens of Junco hyemalis along the creek corridor section, but no trilling chorus just yet. Given the warm temperatures, I half-expected them to be singing — it's just a tad early for that!
Firing up the macro lens for 2024's first insects! Hidden within the winter landscape, resilient Winter Midges Diamesa mendotae showcased their survival strategies. Members of the Chironomidae family, these insects could endure temperatures below -20°C (-4°F) by utilizing "antifreeze" biomolecules in their hemolymph (circulatory fluid). This adaptation allows them to remain active when other insects have succumbed to dormancy. 
The midges are delicate marvels, showcasing their resilience and grace, navigating the frosty air. These tiny insects, just slightly smaller than mosquitoes, contribute to winter's quiet struggle for survival at Pheasant Branch. Their diminutive presence adds a miniscule but crucial element to the harsh winter conditions, showcasing nature's remarkable ability to adapt and endure.
And the creeper creeps on ...
