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 ...
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.
Insects can do this actively through their claw flexor muscle, but in most cases, the foot is able to attach and detach passively, without the help of any nerves and muscles. (Bullock, Drechsler, & Federle, 2008)

Insects that do not migrate must halt their growth to avoid freezing to death, in a process called diapause. [2] Insects prepare to overwinter through a variety of mechanisms, such as using anti-freeze proteins or cryoprotectants in freeze-avoidant insects, like soybean aphids. Cryoprotectants are toxic, with high concentrations only tolerated ...
Tungiasis lesions almost always occur on the feet (97%), but may occur on any part of the body. The toes are afflicted over 70% of the time, with periungual folds (around the toenail) a preferred site. Only once the female burrows into the skin can reproduction occur, as the male and female show no interest in each other in the wild. [8]
Insects and their relatives are hexapods, having six legs, connected to the thorax, each with five components. In order from the body they are the coxa, trochanter, femur, tibia, and tarsus. Each is a single segment, except the tarsus which can be from three to seven segments, each referred to as a tarsomere.
In the post, Holtman says the frog was trapped underneath the tub's plastic seal—meaning the little guy must have hopped in at the ice cream factory well before it made its way to the freezer aisle.
