The problem with Peak is that most of the insects will be in/around the entrance cavern, which would mean you'd need a ladder to find them, assuming John Harrison was agreeable, of course!
Mouldridge and the Bonsall level would be my two to try first, both easy to get to, no access restrictions and without too many hazards. As for the fungi, I'll start looking out - I didn't realise we got zombie ants in this country, I thought that was just a South American phenomenon.
