What does a pubic tick look like? - briefly
A pubic tick is a small, oval arachnid about 1–5 mm in length, with a dark brown or black back and visible legs. After feeding, its abdomen expands and may turn reddish or gray, making it appear larger and more noticeable.
What does a pubic tick look like? - in detail
A tick attached to the hair‑bearing region of the groin presents as a small, oval arachnid. In its unfed (flat) stage, the body measures about 2–5 mm in length, is pale beige to reddish‑brown, and the legs are clearly visible extending from the anterior edge. The dorsal surface is smooth, lacking distinct markings, while the ventral side shows a tiny mouthpart (hypostome) used for feeding.
When the parasite begins to feed, its abdomen expands dramatically. Engorged individuals can reach 8–12 mm, sometimes larger, and become markedly swollen, taking on a rounded, balloon‑like shape. The color deepens to a darker brown or black, and the legs may appear tucked against the body, making them less apparent. The hypostome remains visible as a small, pointed projection at the front.
Key visual cues for identification include:
- Size progression from flat (2–5 mm) to engorged (8–12 mm+)
- Color shift from light beige to dark brown/black
- Oval to rounded body shape
- Visible legs in early stage, reduced visibility after engorgement
- Presence of a mouthpart at the anterior pole
Recognition of these characteristics enables prompt removal and reduces the risk of disease transmission.
