The caddisfly, scientifically known as Hydropsychidae, is a fascinating insect that has captured the attention of scientists and artists alike. In flight, these delicate creatures are attracted to mercury vapor lights, creating a mesmerizing spectacle in Lamar County. Dating back to around 1860, a colorful lithograph showcases various insects including the caddisfly. This depiction highlights the intricate details and vibrant hues that make these creatures so captivating. One particular species of caddisfly, the Salt-and-pepper Microcaddisfly (Agraylea multipunctata), goes through its final larval stage inside a protective case made from secretions. These cases serve as both shelter and camouflage for these tiny larvae. Underwater in River Livet within Glenlivet's Cairngorms National Park, Trichoptera sp. Larvae can be found residing in their larval cases on rocks. These underwater dwellings provide them with safety while they continue their development. As adults, caddisflies can be seen resting on leaves along River Whiteadder in Berwickshire's Scottish Borders during August. Their presence adds beauty to the natural surroundings while showcasing their unique life cycle. Examining caddisflies at a microscopic level reveals astonishing details about their anatomy. Scanning electron microscope images capture C016 / 9107, C016 / 9106, and C016 / 9105 specimens' larvae with remarkable precision. Transporting us back millions of years ago is artwork depicting an Eocene forest landscape where caddisflies thrived alongside other ancient flora and fauna (C016 / 5349). Another artwork (C016 / 3451) illustrates European river life featuring these enchanting insects among other aquatic organisms. Preserved forever in Baltic amber lies evidence of an ancient encounter between a caddisfly and this precious gemstone - an extraordinary snapshot frozen in time for us to marvel at.
