Cabbage white butterfly eggs

A few days ago I noticed that some more eggs had been laid on one of our chilli plants. Following an internet search I think that they must be the eggs of a cabbage white butterfly. All of the blogs that I have read on these say that you should destroy the eggs, rubbing them off with soapy water but I like the idea of encouraging biodiversity through our windowsills and don't really want to go around killing eggs. Is this a really bad idea and will the caterpillars end up munching right through our windowbox?

It also seems that it must have been quite a confused butterfly that laid it's eggs there. From the information on the British Butterfly Conservaton Society's website the eggs are normally laid either on brassicas or on nasturtiums or wild mignonette. So a serrano chilli plant seems a little far removed from any of them!

Itsy bitsy spider

We had a spider visitor to the windowsill the other day. I think that it was a male garden spider (Araneus diadematus) although if you think otherwise then please let me know! It never ceases to amaze me how much wildlife actually manages to find its way up onto our windowsill considering it's only a few small plants but it's wonderful none-the-less. Here you can see one of the chillies on the chilli plant that was placed outside a few weeks ago. That plant has now got six little chillies coming along on it. Still waiting for the big chillies to even look slightly like they are going to start turning red though... They are still looking green as a cucumber!
