Aquatic insects have developed freeze tolerance much like their terrestrial counterparts. However, freeze avoidance is not an option for aquatic insects as the presence of ice in their surroundings may cause ice nucleation in their tissues. [15]: 148 Aquatic insects have supercooling points typically around −3º to −7 °C.
Freezing of the head and thorax in other insects tends to have adverse effects on neural tissue, so it is not surprising that these protective mechanisms have been observed in certain species, but E. nugatoria is the only insect known to semi-freeze through the winter. By allowing the abdomen to freeze, evaporative water loss is reduced over ...
Electron micrograph of housefly pulvilli, the finely hairy pads on their feet that enable them to stick to walls and ceilings. Arthropods, including insects and spiders, make use of smooth adhesive pads as well as hairy pads for climbing and locomotion along non-horizontal surfaces.
But the birds were too far away for me to positively identify them, and in just a few seconds, we'd left the water behind. The brief wildlife ... Why a duck's feet don't freeze in winter and other ...
nymph in Cyprus Walking on water surface; the dark blobs are shadows cast by water disturbances around each of the six legs touching the water.. The Gerridae are a family of insects in the order Hemiptera, commonly known as water striders, water skeeters, water scooters, water bugs, pond skaters, water skippers, water gliders, water skimmers or puddle flies.
The pre-flight warm-up behavior of a moth. Insect thermoregulation is the process whereby insects maintain body temperatures within certain boundaries.Insects have traditionally been considered as poikilotherms (animals in which body temperature is variable and dependent on ambient temperature) as opposed to being homeothermic (animals that maintain a stable internal body temperature ...

Each image was created from around 8,000 individual photographs taken under strobe lights, capturing the insects in high-resolution detail. This exhibit is from the collections of the Oxford ...
