Yellow crazy ant

It moves extremely fast and scatters erratically when disturbed, like a yellow madness, which is why it is commonly called the yellow crazy ant. The exoskeleton is very thin and the body a translucent brown; workers are monomorphic with no soldiers. Listed among the world's 100 worst invasive species, it favours man-made structures within natural settings, such as the base of street lamps, trail edges and drainage pipes. Its formic acid is strong, it is highly predatory and aggressive, and it grows and moves extremely fast, threatening the survival of many native species.
