Bristol University Tick ID

This site includes online dichotomous keys for ticks of the family Ixodidae (hard ticks). It is intended for researchers and veterinary practitioners, primarily in the UK and Republic of Ireland, who wish toidentify tick specimens, or who require information on their morphology, distribution, biology and status as vectors of pathogens. Many of the species of tick included in this website have established populations in the UK and Republic of Ireland, but some are known only from parts of continental Europe or Asia; they are included here because they are important vectors of pathogens and because they are occasionally introduced, for example on travelling companion animals or migratory birds.
