I don't know if I missed this paper at the time, but apparently Swallowtail larval frass (poop) contains a metabolite from the plants the larvae eat that has anti-colon cancer activity.

We had a second attempt at a trip to Tenerife earlier this month (we'd both been really ill when we visited last year). This time a bigger, family affair to celebrate my entering my seventh decade.

A few wildlife snaps and scenery shots

One from last summer #teamMoth to cheer myself up on these chilly mothless nights

Eyed Hawk-moths are among our biggest moths. When its forewings are covering its hindwings, the head with its dark markings might ward off a predator, because it looks like a furry face staring back, but if that doesn't work, then it flashes the ocelli (false eyes) on its hindwings and that often does the trick. #pareidolia
