It's Friday Fly Day and time to post a syrphid fly with a butterfly.

The occasion: a syrphid fly and the Gulf Fritillary (Agraulis vanillae) or passion butterfly are sharing a Mexican sunflower, Tithonia rotundifola, and neither seems bothered that the other is there.

Holes in the petals indicate that another insect, perhaps a spotted cucumber beetle, had been there.

The Mexican sunflower is like a giant floral billboard in a pollinator garden.

"Hey, insects, here I am. Come visit me. I have pollen and nectar for you. I just ask for your pollination services. I can't give you a hug or a certificate of appreciation or even a participation trophy, but I can give you a thank you in the form of free pollen and nectar. That's your reward. And tell all your friends that I am here. I am the billboard in the pollinator garden."

Happy Friday Fly Day.
