About

Also called the deer tick, this arachnid is the primary carrier of Lyme disease in eastern North America. Its poppy-seed-sized nymphs are the hardest to spot and cause most human infections, often picked up brushing through backyard leaf litter or tall grass.

    egg sac
    A silk-wrapped egg sac shelters a clutch of eggs until the young are ready to emerge.

    A spiderling emerges from the egg sac already in miniature adult form and starts catching prey almost immediately.
  3. 3.
    subadult
    A near-adult arachnid molts through several instars, growing larger and developing mature markings.
  4. 4.
    adult
    Fully grown after its final molt.
