We introduced them into the arena around 2330h last night and conducted the test this run at 0900h - The male was extremely passive with no aggressive interactions - meaning has she stumped... (see data sheets for details) July 21 This am on GRID RC we caught ♀O20, st 10,10. She was inside the trap but her tail (last 15mm) was caught in the door. She seemed okay, but she had lost 10g since yesterday. She gave birth between the 25 and 27th of June, put on 5g yesterday, so perhaps she gave birth!? This would be an interbirth interval of 24-26 days - very short. (See notes July 22)
