Red bug on green plant

Such is the extent of my knowledge of horticulture and entomology!

On the bike today, hooray! Fingers crossed knee no more than tired after exertion, certainly no wobbles or sudden stabbing pains, and I went up and down the four flights of stairs to and from my office several times today without any more than a niggle.

I'm sure there will be some wise blipper out there who will tell me what the red beetle is? I think you may have to go LARGE.
