new and strange

There are new flowers growing in my yard. I think they're gladiolas. These are plants that come up year after year, someone planted them here before we owned the house. In the front is a lovely pink spray

and in the back a red one so brilliant it looks unreal.

And I found a very strange, decorative insect on the window outside. I've never seen such crazy colors on a bug- it makes me think of a snake, for some reason. Is it a nymph of some kind?

what is this bug??
