Garden wildlife!

Today we are mostly be doing Hedge Trimming! (for those that don't know The Fast Show it's loosely from that, rather than my bad grammar!).

After completely filling up the 'Green Bin' (Garden rubbish which is composted by the Council) I rolled it back to the place I keep it and opened the lid. That's were I found the small red spider. I've tried to find what kind it is but no luck.
And then I spotted hundreds of caterpillars on the Rocket. I'd been finding the odd leaf with tiny orange/yellow coloured eggs but when I've been picking the Rocket lately there are lots of small holes in the leaves. I found a few tiny caterpillars but today I spotted some that are grown up already, and still some tiny ones.
I'm not going to spray them, or pull up the Rocket and bin in as I'm sure they are the caterpillars of small white butterflies which I've seen flying around in the veg garden for the past couple of weeks. Butterflies don't appear to be as numerous as they normally are so I'm just letting nature take it's course. I can always plant more Rocket seeds.
