There are seven different types of urticating hair known in tarantulas, varying in size and shape, particularly the distribution of barbs. [11] Type I (0.2–0.6 mm) Type II (0.5–1.5 mm) Type III (0.3–1.2 mm) Type IV (0.06–0.2 mm) Type V; Type VI; Type VII; Each type of urticating hair is believed to target different enemies.
The larvae – caterpillars – have a toughened (sclerotised) head capsule, chewing mouthparts, and a soft body, that may have hair-like or other projections, three pairs of true legs, and up to five pairs of prolegs. Most caterpillars are herbivores, but a few are carnivores (some eat ants, aphids, or other caterpillars) or detritivores. [2]
Caterpillar hair has also been known to cause kerato-conjunctivitis. The sharp barbs on the end of caterpillar hairs can get lodged in soft tissues and mucous membranes such as the eyes. Once they enter such tissues, they can be difficult to extract, often exacerbating the problem as they migrate across the membrane. [34]

The female is slightly larger than the male in larva form, and as an adult finds a mate by extruding an organ that emits a pheromone which the male can smell. The male, which unlike the female has the large, feathered antennae characteristic of pheromone-using moths, flies zigzag search patterns, eventually homing in on a female.
The spiny caterpillars are striking in appearance, with black bodies and a line of eight reddish-orange dots running down the back (aposematic, warning coloration). The prolegs are dark red. The body is covered with short hairs and black spines and white dots. [2] The fully grown mourning cloak caterpillars attain two inches in length. [3]
