Sunday Sketch: Swallowtail Caterpillar
Swallowtail caterpillars are masters of mimicry and masquerade. While most swallowtails look convincingly like bird droppings at earlier instars (developmental stages), older caterpillars often develop a snakelike appearance to scare away predators. Their intimidating eyespots work in tandem with defensive behaviors (thorax inflation, rearing up, scent gland eversion) to create a compelling mimicry! Who knew…

Sunday Sketch: Sleep to Prevent Late-Night Cravings
Hummingbirds have high metabolic energy requirements, needing to eat 2-3x their own body weight in flower nectar and tiny insects each day. Unable to forage at night, but needing to maintain those demanding energy requirements, hummingbirds conserve energy by going into torpor. This physiological adaptation is a daily version of seasonal hibernation, and is a deep…
Deep breath in!
Unlike human nostrils which remain open at all times, the relaxed nostril position for pinnipeds is in a closed position. Like this harbor seal (Phoca vitulina) they voluntarily open them when at the surface of the water to sniff or breathe.
