Several Female deer ticks partially engorged, to show color and size variation. Largest is 10mm. The hypostome broke off when this tick was removed from our cat. We remove ticks from people with an X-Acto knife, see this paper for details. Ticks and a common pin along with forceps for scale. Compare to the theoretical removal method here. The deer ticks shown are l-r: adult, nymph, and two larvae mounted on a microscope slide.
The smallest stage, the larvae are also known as 'seed' or 'grass' ticks, while latter stages are often referred to as 'bush' ticks or 'shellbacks', but all of these terms refer to the same animal. The unengorged adult female is around 4mm long, the nymph around 2mm, while the larvae are less than 1mm. Male Ixodes ticks Male Ixodes holocyclus left and male Ixodes cornuatus right.
