A katydid dines on the bruised pink petals of rose Mrs Doreen Pike. The long antennae assist navigation at night. Because they are often nocturnal and usually well hidden, I don't often see katydids. This one was easily seen perched on its pink meal but the bright green colour and vaguely leaf-like appearance made it pretty difficult to spot when it moved back under the rose leaves.
Another beastie spied on a rose was less camouflaged, but much smaller and harder to spot for that reason...
It seems to me similar in shape to so-called square ended crab spiders. This tiny white spider perches on a rosebud - probably waiting for tiny prey. The rose is safe - no veggies for this meat-eater!
