I spotted this 6-legged dual winged insect in my Southern California backyard today. It is about 2-1/2" in length and has two brilliant orangeish-red wings. Today was a cool day about 65* overcast and I've never seen anything like it before! Once I got close enough to snap a couple of photos, it then flew off. What the heck did I observe today? Will I likely see any more?
Many thanks for your help.
