You were right to question my measure. It appears I have a CM concern. After pulling this one out of the jar, it was clearly >10mm, and significantly bigger than the other Libra I posted. I measure most beetle virtually these days (some would say I've been virtually measuring all along, no doubt). But to do that accurately, one must use the correct measure. Turns out I switched cameras between the smaller Lebria and the larger one, to achieve a wider field, but used the same narrower field's measure on both beetles.

how grand it is.

I blunder with measurements sometimes too. :)

Forgive my move, seems we both moved it at the same time.
