How does a tick know when it has reached the back of my dog's neck?

The best suggestion yet, from my friend Massimo, is that ticks feed on arterial blood and they use some sort of heat-seaking mechanism to go where the vessels are nearest the surface. Plausible, but I don’t buy it. Not yet. Not entirely.

I very much regret that Russian spammers have made my comment system unusable. If you want to email me a comment, it is easy enough to find the address and I will be happy to do the needful behind the scenes. Webmentions remain available (for now).
