Antarctic Midge
The only insect endemic to Antarctica and the continents largest purely terrestrial animal at 2-6 mm. Wingless, freeze-tolerant, and can survive temperatures down to -15C.
Did You Know?
This midge has the smallest known insect genome at 99 million base pairs — 97% smaller than a mosquito, likely an adaptation to survive extreme cold with minimal energy.
Brassy Willow Beetle
A small, shiny metallic bronze to greenish beetle that feeds on willow and poplar. Adults overwinter in leaf litter and emerge in spring to colonize new willow growth.
Did You Know?
Larvae secrete salicylaldehyde, a chemical obtained from salicin in willow leaves, which smells like antiseptic and deters predators.
