Came across this beauty while on my morning walk. I think it’s some sort of robber fly? He/she was quite large (the reason it caught my eye) and not interested in moving even when I brushed it with a blade of grass. It was early morning so maybe still sleepy? Anyway, I’d love to know what to call it the next time I see one.
Thanks so much!
Your Robber Fly looks like a Red Footed Cannibalfly, Promachus rufipes, to us. We generally get several identification requests for this magnificent predator each summer.
