Found it on my son's hair after a 10min visit to our veggies garden. My guess is that it might be a tick but we are not in an area of lime disease and although it's an open, rather unkept, field the only mammals I see around are 2-3 stray(?) cats.
The photo was done using a stereoscope+smartphone. The dark lines underneath are .4 to .5 mm.
Any pointers would be welcome.
Wikipedia is a good starting point, then you have this
https://parasitesandvectors.biomedcentral.com/articles/10.1186/1756-3305-3-26
And you can also search online for how to ID ticks, you have visual guides and such
Thanks! Had seen that paper once you guys pointed me to R. sanguineus and I had a chance to shower the kid.
I also found this site useful for ticks anatomy, on TicksSafety.com.
