My friend Paul told me that a cat without fleas does not exist ! I am quite ready to follow him on that. But could we say the same for lice ? Personnaly I admit that I have never seen any louse in a cat fur. Anyway our dear cats have actually their lice, like we humans have ours…

I am pretty sure that you have never seen them, at least such big ones ! Anyway, this Felicola subrostratus species is petty much illustrated on Google image. On that specific topic I will not bring a brand new iconography to the net, but the photos are worth seeing, with the sexual dimorphism… You will now have an example of a male and a female to distinguish them, if you happen to find some in your cat fur !

This species is belonging to the Trichodectidae family. It is yellowish, with brown transverse bands, with a head subtriangular, and antennae have three segments. It is around 1mm in length. It might be present all around the world probably due to the release of the domestic cat.

Do not hesitate to submit us your cat lice (in alcool of course, otherwise it could infest the bloody Garfield which is always rummaging about in my compost !).

Many thanks again to Paul for these outstanding photos (and outstanding microscopic mounts).

Cheers !

Slender pigeon lice are primarily found in the feathers on wings of pigeons. It is the typical parasite for Columba livia, but many other types of lice can be found on it.

Here are again remarquable photos from Paul Leroy of this very common parasite.

This species is belonging to the family of Philopteridae. With the same name of the family, I understand they like the wings (Philo-pter) of their hosts, as it is where they are usually found…

You will much probably never see all the species of this family on mites-and-parasites.org as there are 138 genera and 2945 species according to phtiraptera.org, at the date of publication of this post.

This species was, is-it original ? first described by Linnaeus !

I pinpoint this strange document on behaviour of pigeon louse which had been studied by M. Rakshpal, for different types of smells, temperatures and contacts.

Our dear Linnaeus first described this species under the name Pediculus pubis. The first question I ask to myself is a little bit disrespectful towards our dear Linnaeus : where did he found his first Pediculus pubis ?

You do not know ? Ok, maybe you do not know at all, where usually lives Pthirus inguinalis ? But if you already know, Pediculus humanus, you can easily imagine where lives Pediculus pubis. Do I need to give you some more explanations ? Come on…

Actually we can find all sort of different orthographs and synonyms for this immodest parasite, and I admit I still have difficulties in writing its correct name :

  • Pediculus pubis
  • Pediculus ferus
  • Phtirus pubis
  • Pthirus pubis
  • Phthirus chavesi
  • Pthirius inguinalis

I will keep this one, from the very serious site http://phthiraptera.info/ : Pthirus inguinalis. And this is probably the official stable name for this little big louse ! You just have to remember well where is the H, and where there is no I !

I am happy to share with you tree outstanding photos of this Pthiridae from my dear friend Paul Leroy. Enjoy the fine details, and the ugly beauty of these crawlies, enjoy the forthcoming little baby, already with its strange scissors !

Haematopinus suis

This parasite is spread all over the world, probably because it was brought by human with the introduction of porks. Originally, this is the type louse of boar (Sus scrofa). I am glad to show you today two outstanding photos of Haematopinus suis, made by an outstanding microscopist, Paul Leroy. It seems that the Haematopinidae […]
