Nice

I dug around in my folders just now too, and found a pic of one of the red damselflies that you said you spotted, this pic was taken the same day as my photo of the big critter at the exact same spot...

Took this new critter pic recently...

Well, its definitely a Shield Bug ( no great expertise there)
Probably a green Shield Bug, who have the trick of turning from green to brown in the autumn (feels like it to me,) just like the leaves.
If anyone knows better I will be pleased hear from them

Well, this critter pictured needs no introduction, but i have posted it here because this year, the population of 7 spot ladybirds in Warminster seems to have exploded.

I haven't seen as many ladybirds as this in years, and it's quite unusual, especially when you consider the lack of butterflies during this summer.
