hi mantidlord! i am in silicon valley - sunnyvale. you had sent me some m religiosa last year and iris oratoria. (btw, we had an ooth from the religiosa collection that did hatch!)
this chinese (a HUGE one) ) was just sitting on my recyling bin - she's a bit raggedy looking, but very healthy and looks like she had just laid an ooth - as it appears there is still some residual ooth material. we aren't near any nurseries, all residential. the only mantids we've seen in the area are the religiosa.
she is so big that i saw her from the corner of my eye and thought it was a big lizard. totally caught me off guard. i've been looking to see if there are any others in the vicinity, but so far, nothing.
