    Even linearized, the inchworm was barely 20 mm long; it’s the thought that counts.

    The stamens mature in concentric rings, each stamen topped by a pollen grain. Apparently, those grains are just about the most wonderful food ever, as the inchworm made its way around the ring eating each grain in succession:

    Of course, what goes in must come out:

    I had to brush off the table before washing it; the pellets are dry, but smear when you get them wet.

    Another flower in the vase held a 10 mm inchworm with plenty of upside potential:

    After nearly a week, the flowers were done and the inchworms had moved on. We wish them well, although we likely won’t recognize them in the future.
