Haemaphysalis concinna is a common rodent tick species that originally predominantly occurred in Russia and Eastern Europe, [1] but is also known from Japan, China, Germany and France. [2]
It is known to act as a vector of tickborne disease. [1]
Females reach a length of three to four mm, but can grow up to ten mm when engorged; males are about three mm long. An unfed nymph is under two mm long. There are more males than females. [2]
The tick can be found in the warm temperate climate zone of deciduous and mixed forests across Europe and Asia. It prefers moist habitats lake shores or river banks. [3] In China, it has been found in northeastern regions including Liaoning, Jilin, Heilongjiang, and Inner Mongolia. [4]
All three stages target different hosts, the eggs are laid on the ground. They mate on their host around April. [2]
Nymphs and larvae feed on small mammals such as rodents or hedgehogs, or on birds, reptiles, and humans. Adults prefer larger mammals, ranging from cats to horses, again including humans. [2]
H. concinna can act as a vector for Francisella tularensis (causing tularaemia), Rickettsia sibirica (Siberian tick typhus), Rickettsia heilongjiangensis (Far-Eastern spotted fever), Virus of Russian spring-summer encephalitis (RSSE) and tick-borne encephalitis (TBE). [2] It is a likely vector of Wetland virus. [3]
