About ticks, mites & other arachnids
The lone star tick is one of the ticks, mites & other arachnids. This group includes ticks, mites, scorpions and harvestmen. Like spiders, adults have eight legs and no antennae, though larval ticks and chiggers have only six. Ticks and some mites feed on blood or skin, while scorpions hunt insects and harvestmen scavenge.
Ticks move through larva, nymph and adult stages, and each stage needs a blood meal. Nymphs are tiny and active in late spring and summer, which is when many tick-borne infections happen.
