Nymph-stage Ixodes scapularis (a.k.a. blacklegged or deer tick) Growth Comparison

Nymphs are active May-August, and are most commonly found in moist leaf litter in wooded areas, or at the edge of wooded areas. The eight-legged, pin-head sized nymph typically attaches to smaller mammals such as mice, voles, and chipmunks, requiring 3-4 days to fully engorge. Nymphs also readily attach to and blood feed on humans, cats and dogs. Once fed, they drop off into rodent burrows or leaf litter in animal bedding areas where they molt and emerge as adults in the fall.
