This very small bright beetle caught my eye as it flew past my knee into a clump of grass. It was active, moving from one grass blade to another, typically crawling upward a few inches then launching itself to the next. When I got really close, it started "hiding" behind the grass blade it was crawling on, but this is a very fine-leaved meadow grass that didn't offer much hiding space. So I got a shot of its underside (next image.) I thought it might be a blister beetle of some kind (the bright colors) but those seem to be longer and slimmer, with lengthwise stripes if they have stripes. It was out in midday, in bright sunlight, too.
