While their function is not known, the presence of festoons helps distinguish all other types of ticks from Ixodes ticks, which lack festoons. Festoonsįestoons are small areas separated by short grooves located on the back margin of the tick. The shape and length of mouthparts can be a useful aid in tick identification but unfortunately, mouthparts often break off (because of the backward pointing barbs on the hypostome) and are left in the skin. The length of the mouthparts is one factor contributing to how hard or easy it is to remove different types of ticks. The damp paper towel and tick should then be placed in a plastic bag and sealed. Wrap the tick - suspended in masking tape - in a damp paper towel. Use a piece of masking tape to suspend/trap the tick. Instructions for submitting the tick (s) for identification. Some ticks (notably blacklegged ticks and lone star ticks) have longer, straight mouthparts, while others have shorter straight (American dog ticks, Rocky Mountain wood ticks, Pacific Coast ticks) or shorter triangular-shaped (brown dog ticks) palps. Tick Identification is available through the University of Maryland. A pair of chelicerae (pronounced chel’icery) are located at the tip of the hypostome the chelicerae work like a reciprocating saw to cut a hole in the skin into which the tick sinks its hypostome lined with rows of backward pointing barbs, which help hold the tick tightly in the skin while it blood feeds. When a tick attaches to a host, the palps fold back, exposing the hypostome (a tick’s mouth). The most distinctive components of the head are the palps and toothed hypostome, collectively called mouthparts. Ticks have 2 distinct body regions, the head (capitulum) and the body (idiosoma).
