The larva is pale orange in colour and feeds on liquified skin tissue, not blood, as their mouth parts (chelicerae) are too short to reach the blood vessels. They have 3 pairs of legs. The larvae most commonly target rodents, but will also attach to humans. For humans, the bite is painless, but pain commonly develops only after the larva detaches from the skin, leaving a red papule that may then develop into an eschar.
The larval stage lasts for 1 to 2 weeks. After feeding, the larvae drop to the ground and become nymphs. Nymph is brick-red in colour and has 4 pairs of legs. Nymphal stage lasts for 1 to 3 weeks. Nymphs mature into adults which have 4 pairs of legs, first pair being the largest. They are harmless to humans. In the post larval stage, they are not parasitic and feed on plant materials. Female lays eggs singly, which hatch in about a week. Lifespan of adult is about 6 months.

Famous quotes containing the words history and/or life:
“The history of philosophy is to a great extent that of a certain clash of human temperaments.”
—William James (18421910)
“In time, after a dozen years of centering their lives around the games boys play with one another, the boys bodies change and that changes everything else. But the memories are not erased of that safest time in the lives of men, when their prime concern was playing games with guys who just wanted to be their friendly competitors. Life never again gets so simple.”
—Frank Pittman (20th century)
