Longhorn

I've not a scoobie doo what this beetle actually is, other than that it is green and has very long antennae so is probably a longhorn beetle of some sort.  

As you can see, it seems to have eaten too much, as its green carapace has apparently split showing a shady coloured interior.  In fact the beetle is the same on the other side, so I don't think that this is really a case of a beetle needing to go on a diet.  Its sitting on an Oxeye Daisy, to give you an idea of its size.

It has been a funny day weather wise, a relatively fine start followed by intermittent torrential showers, but not that warm for nearly June.  Hopefully the weather will warm up a bit shortly.
