What's the earliest instar for sexing scorpions?Other than Centruroides.I seen an add that had the sex listed 2.2,they were second instar.Can you possibly tell at that size?
I think it might be interesting to look at,and compare the pectines of different species 2i until adult hood.See when if any changes in them happen,and document at what instar it happened.What would be the best way of seeing the pectine teeth of something that small?It just got me curious after seeing that ad.Thanks for all the replies.
This has been done at least once. Polis and Farley examined the growth of pectines in S.mesaensis over time (it should be noted that the number of teeth is constant, but the length does change with time). Basically it was shown that the rate of growth is more-or-less constant in both sexes when they are young but takes off dramatically in males towards maturity. A stereomicroscope with a reticule would allow you to take all the requisite measures to conduct a similar study on any species you wanted to. Obviously you would need a large number of specimens to make the results meaningful. It would also be important that the identity of the specimens be certain and that they are not all related.I think it might be interesting to look at,and compare the pectines of different species 2i until adult hood.See when if any changes in them happen,and document at what instar it happened.What would be the best way of seeing the pectine teeth of something that small?It just got me curious after seeing that ad.Thanks for all the replies.
