If you live in the West,

If you live in the West, Julianna, you may well have Flame Skimmers (Libellula saturata), also called Firecracker Skimmers. The males are bright orange and the females duller brown, so you may have two pairs, in fact. They are likely laying eggs in the koi pond--the youngsters burrow down in the mud eat all sorts of aquatic insects. Your pond has probably hosted many many generations of these dragonflies!
