Lone Star Tick (dead) - Note the white spot. They are not common in CT (yet) so I have only pictures sent by readers of this site who asked about the tick type. The Lone Star tick is similar in size to a deer tick but has a white spot on its back. ![]() The deer ticks shown are l-r: adult, nymph, and two larvae (mounted on a microscope slide).

The numbered scale shown in most of the pictures can be used to judge the exact size but you must be somewhat familiar with the tick type to determine which objective was used to take the picture - 250/100/25 microns per numbered division (1000 microns=1mm) are produced by the 4/10/40 power objectives respectively. All you need is a 10 power magnifier to determine whether a deer tick is a larva (6 legs, unlikely to carry Lyme) or a nymph or adult (8 legs, commonly infected with Lyme and/or other tick borne illnesses here in CT) - read the paper on this site for more info. Most people are not familiar with deer ticks and cannot tell a deer tick from a dog tick - the goal here is to help in identification as well as to provide information on how to tell when a tick may be carrying Lyme disease and when it is very unlikely.
