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 ...

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 ...
They can travel 0.5 m in a four-day period. [12] They lay their eggs on carrion to provide food for the hatched larvae. Often, Megaselia scalaris may be the only forensic entomological evidence available if the carrion is obstructed or concealed in a place that is hard for other insects to reach. [13]
