Notes

So I don't forget what happened tonight.

Uroctonus mordax mating attempts:

Male B, female 3:
Male approached female under bark, male later upside down hanging from bark, pair later upside down, no promenade observed, male coaxed female onto bark. Upon examination for spermatophore, pair separated. Male later returned under bark, last seen as both under bark (male's rear protruding), cannot tell if pedipalps are grasped. Will leave overnight and examine for spermatophore in morning.

Male C, female 4:
Male initially very confused about where to grasp female; wrong pedipalp and leg, metasoma and leg, both pedipalps wrong while sitting astride female. Eventually gave female a brief sexual sting in the membrane behind the left chela. Unsuccessful sexual sting behind right chela followed by extended sting behind left chela (greater than ten minutes). After this observed extended promenade a deux -- sometimes grasping one pedipalp, sometimes both, a few instances of cheliceral kisses on the part of the male observed as well. Male walked both across provided bark and bare substrate. No spermatophore observed as of yet. Will leave overnight and examine for spermatophore in morning.

Male D, female 5:
Male did not notice female's burrow initially. When directly introduced, female came partway out. Apparent standoff ensued, with both specimens metasomas raised and periodically waving pedipalps (video forthcoming). Female briefly grasped male's pedipalps. Pair separated to prevent injury; male now believed to be large subadult as opposed to initial assumption of small adult.

Centruroides sculpturatus:
Several juveniles wandering off female. Majority swept from female's back prior to moving her to a separate container. Will hopefully separate all second instars tomorrow evening. Current brood size estimated at >20.
