The Frit and the Fly: Who Wins?
The Frit and the fly...or the butterfly and the fly... That would be the Gulf Fritillary (Agraulis vanillae) and the syrphid fly (family Syrphidae), aka flower fly or hover fly. They meet on a beautiful autumn day on an equally beautiful Mexican sunflower (Tithonia...

Autumn's Majesty: Tithonia
If there's any flower that should be crowned "Autumn's Majesty," that would be the Mexican sunflower (Tithonia rotundifolia), aka "Torch."A member of the sunflower family (Asteraceae), it carries "the torch of life" throughout spring, summer and autumn, but it's especially important in autumn when...

A Fly, Oh, My!
A fly, oh, my! On the approval scale, they don't rank nearly as high as honey bees, but some are often mistaken for them. Take the Eristalis stipator, which belongs to the family Syrphidae, the hover flies. It's about the same size as a honey bee and it's a pollinator. We recently spotted this...
