The Weta is one of the largest and heaviest insects in the world. They are found in a wide variety of environments due to their ability to cope with variations in temperate. They have large jaws and are known to hiss and bite when threatened.
Inflatable scent glands called
coremata are especially common in male tiger moths and wooly bear moths. These plumes, when inflated with either air or blood, release chemical pheromones to lure in potential mates.
Since the ban on the powerful, but dangerous pesticide DDT in 1972, chemists have been searching for alternatives. With each new wave of inventions, they’ve encountered the same obstacle - rapid species evolution. As pesticides destroy pest populations, they leave behind only the most resistant individuals. Those remaining bugs then pass on their pesticide-resisting genes to the next generation. That’s lead to the rise of super bugs, such as the Colorado potato beetle, which is resistant to over 50 different insecticides.
