Yup, buzz-buzz-swat-buggers. Now, I can't guarantee you're going to come out of this one in love with flies (and fleas), but maybe you'll think a wee bit differently about 'em. About what we need to do to our brains to make small buzzing things our chums, not our nemesis. And why needing to do it is pretty dang essential for not wiping out everything that lives, including ourselves. Joining Dave this week is the legend that is Dr Erica McAlister, the London Natural History Museum's expert on all things dipeteric (flies) and siphonapteric (fleas). Never will you have been so charmed by one woman's protective affection for these unloved insects.  Owl noises: -- 08:07: if you want more secret sexy fly stuff, you perv, check out Erica's talk on Youtube.-- 29:52: an obituary of Miriam Rothschild who believed in God because fleas have willies.
