I'm very sorry to hear about this. I can't imagine what that must feel like. Now while a mental issue could be the case this seems like it was done with an intent, I would take the whole 'of no importance' thing as a way of saying if they were important you should have gotten them sooner.
If you feel this was the case then by all means give her a bill, she may not pay for it, but she will probaly never understand the emotional connection you had for the spiders. Putting a finicial value of them in front of her would give them some value in her eyes and possibly help her understand how wrong what she did was.
