Have you ever seen such a perfect microphotography of a tick ? This is the astonishing work of Paul Leroy again. Here is a female of Ixodes ricinus, commonly called the castor bean tick, this name sounds funny for the French speaking guy I am…
This tick has a very large distribution in Eurasia and is probably the most common tick found on people.
A female fasting tick has usually a size of 4 mm. The scutum is globally rouded, and slightly longer than large, as you can see on the photo. The posterior margin of the body is largely rounded, which gives this typical shape of castor bean (castor seed is a better appropriated term).
Each pair of coxa has an external short spur. The coxae I have a long internal spur. Coxae I are syncoxae, but the striated half posterior part is slightly visible.
Ixodes ricinus is an ubiquitous triphasic tick. It feeds on a wide variety of vertebrate hosts and is a vector of numerous pathogens (Flavivirus, Borrelia, Babesia, Rickettsia, Anaplasma, Louping ill,…).
Enjoy this outstanding photography, it looks like a very good color drawing !
