Today's creature feature is the dragonfly. Dragonflies were some of the first winged insects to evolve, some 300 million years ago. Modern dragonflies have wingspans of only two to five inches, but fossil dragonflies have been found with wingspans of up to two feet.Dragonflies have complicated neck muscles which allow them to tilt their head sideways 180 degrees, back 70 degrees and down 40 degrees. Dragonflies can hover in midair and then rapidly accelerate.One article suggests dragonflies are the most effective predators in the animal world – 95% success rate which is truly amazing.

Bee or wasp? Take a closer look!Masked Bees (Hylaeus spp.), also known as Yellow-faced Bees, are among Wisconsin's smallest native bees, measuring just ¼ inch long. Their shiny black bodies, bright yellow facial "masks," and lack of fuzzy hairs often cause them to be mistaken for tiny wasps.Unlike most bees, female Masked Bees don't carry pollen on their legs or abdomen. Instead, they store both pollen and nectar inside their crop—a specialized food-storage organ—and transport it back to their nests. Because they don't have the pollen-carrying hairs (called scopa) found on many other bees, they have a sleek, almost wasp-like appearance.These tiny pollinators nest in hollow stems, twigs, and other pre-existing cavities, lining each brood cell with a remarkable waterproof, cellophane-like secretion that protects their developing young. Since they can't excavate their own nests, they often rely on tunnels already created by other insects.With nearly 700 species found worldwide and about 14 species in North America, Masked Bees are widespread but frequently overlooked. In Wisconsin, they can be found from spring through early fall, quietly visiting a wide variety of flowers.The next time you notice a tiny black-and-yellow insect on a blossom, don't assume it's a wasp. It just might be one of our smallest—and most fascinating—native pollinators!Photo is of a close-up of a yellow flower with a small black bee on its stamens, highlighting the flower’s vibrant colors and details with the Wehr Nature Center logo in the lower left corner.
