L. Koch, 1844 }}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] DescriptionFemales 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] DevelopmentAll three stages target different hosts, the eggs are laid on the ground. They mate on their host around April.[2] Feeding behaviorNymphs 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] DiseasesH. concinna can act as a vector for Francisella tularensis (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]References1. ^1 {{cite web | url=http://www.wrongdiagnosis.com/medical/haemaphysalis_concinna.htm | title=Haemaphysalis concinna - RightDiagnosis.com}} 2. ^1 2 3 4 {{cite web | url=http://webpages.lincoln.ac.uk/fruedisueli/FR-webpages/parasitology/Ticks/TIK/tick-key/background_haemaphysalis.htm | title=Staff Pages - YOUR NAME HERE}} External links
