Spike here was about 15mm long, and sitting in the middle of a plank on the deck. I couldn’t get the camera low enough for a great angle, and hey, I wasn’t going to touch it. A cautious attempt to encourage it on to a leaf with another leaf just resulted in a small bidibid shaped ball of caterpillar rolling around on the deck. So, sorry, this is not the best photo composition ever, but it is a view of one of the most interestingly strange minibeasts currently in my garden, the yellow admiral caterpillar, with this one likely a little lost on a trek to find more nettles. Photo with the 4:1 20mm lens.
