Are you sick of throwing your self on the altar of unrealistic magnificence requirements? Do you lengthy to rejoice the delightfully monstrous, to provide the spiny stuff of shadows their day within the solar? Then think about the mighty wētāpunga – an endemic New Zealand insect so revered for its unconventional magnificence its title means “god of ugly issues”.
This forest behemoth is considered the heaviest grownup insect on the planet, with a feminine weighing as a lot as a mouse or a sparrow. Its physique can develop as much as 10cm lengthy (almost 4in) and its leg span may be as large as 20cm. As soon as discovered throughout elements of the North Island, the susceptible wētāpunga – the biggest of 70 wētā species – now resides completely on a smattering of predator-free islands close to Auckland.
Its Latin genus title Deinacrida could translate to “horrible grasshopper”, however the wētāpunga’s bark is greater than its chew. Actually, it doesn’t chew to discourage predators, nor can it fly, bounce or kick. As a substitute, this docile large makes use of its stomach and legs to supply a stridulating hiss when disturbed – a method that has helped guarantee its survival, nearly unchanged, for greater than 190m years.
If in case you have a smooth spot for the shy and elusive amongst us, you will see a good friend within the wētāpunga. This solitary creature with large, sort eyes tiptoes by the forest at night time in quest of leaves to eat, utilizing its spectacular spiny legs and dainty hooked toes to grip on to bark and leaves.
Not one to make a present of itself, the wētāpunga’s mottled tan and inexperienced exoskeleton blends into the muted browns of its habitat. By day it hides itself away in fallen leaves and timber.
It can be a diplomat: regardless of kiore (pacific rats) having a style for child wētāpunga, or nymphs, grownup wētāpunga have been identified to share lodgings with their furry adversaries. Maybe it is a nod to its former ecological function: previous to the introduction of rodents to New Zealand, wētāpunga have been thought of the “mice of the invertebrates”.
It might be adept at residing within the shadows however there may be one technique to know if you’re within the presence of greatness: search for wētāpunga poo on the backside of timber. Adults have faeces as large as rat droppings – the most important of any invertebrate, and one of many largest in relation to physique measurement within the animal kingdom. That is nothing to smell at: the nutrient-rich wētāpunga poo does wonders for the forest-floor ecosystem.
The wētāpunga could favor a solo life, however it’s not proof against the forces of affection. As soon as it reaches maturity, simply earlier than two years of age, it spends the remainder of its life (one other 4 to seven months) mating repeatedly all through the day. Females lay eggs within the smooth soil, which upon hatching undergo 11 instars (moults) earlier than reaching maturity.
These mild giants are presumed extinct on the mainland of New Zealand, after predation from launched species and habitat loss. Captive breeding and launch programmes are serving to to spice up populations on offshore islands.
