Hello world,

Here is a ventral view of a male of Haemaphysalis punctata. This tick is widespread in Europe but can be found also in central Asia.

The male has very long internal spurs on the coxas IV, as you can notice on the enclosed remarquable photo done by Paul Leroy. The tick shown appears differently as other ones you can find on the internet, because this is a microscopic mount, and the animal has been cleared to reach semi transparency.

According to the site quoted here below, this type of tick shows no preference for environment and can live in humid / cold, or warm / desertic environment. This is probably due to some specific adaptations…

According to an Ukrainian study (see here below), it can be found on very different types of hosts (wide range of mammals, birds, but also occasionnaly on reptile). Common hosts in human environment : cattle, sheep, goat, horse, deer, rabbit, humans…

As other ticks, it can transmit several types of diseases :

  • Rickettsia siberica,
  • Tickborne encephalitis virus
  • Babesia bobis, B. bigeminum…
  • Theileria mutans, T. recondita…
  • Coxiella burneti
  • Brucella melitensis
  • Bhanja virus
  • Francisella tularensis

With such diseases transmitted, it raises the question of good and evil. Is such a tick good or evil ? How can we accept the fact that such a being could have a benefic role in the animal reign diversity ? If you have your aswer to this question, let me know !
