At last.

I've been trying, for lo these many moons, to catch a "half-waxed Starky".
As juveniles they are uniformly drab.
As adults they are/can be quite splendiferous if caught in the right light. I've  seen a few obviously manipulated beyond all recognition until you'd swear they were a glamorous tropical exhibit.
Then there's this half-way stage, when they look like yet a third species, with the uniformity of youth and the " negativised" Dalmatian flanks of an adult. By another serendipitous fluke there's an adult hard by for comparison - of sorts.

I chucked in a bonus, just as a record for me. I couldn't display the whole spike to suit me, but I can at least boast the size of the flower(s). This ie the one which, unusually for me went mad with three simultaneous Spikes.
