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.
Ticks exist outside of Lyme disease zones. And it's easy to pick them up in fields where animals roam. Doesn't even have to be high traffic. Plus, there was recently news that the little buggers can use static electricity to passively "jump" onto animals and humans, which is just extra annoying.
Are you looking for a species ID? I'm not trained in such things, but I can try to search up similar critters if you like, but it's definitely a tick of some variety.
Edit: did a quick search for poo and giggles (and ticks). Looks like a brown dog tick
I think this is the best guess, it checks out especially with the head shape and geo distribution.
