Bug Squad

When a tiger meets a Tithonia, or a Tithonia meets a tiger, Nature bursts forth in all its glory. Such was the case when we spotted a Western tiger swallowtail, Papilio rutulus, foraging for nectar on a Mexican sunflower, Tithonia rotundifola, in a Vacaville garden.

The Gulf Fritillary, Agraulis vanillae, and the Mexican sunflower, Tithonia rotundifola, seem made for one another. Both are a showy orange. Both are show-stoppers. And both attract a photographer's eye. Especially when a Gulf Frit flutters over a Tithonia on a warm sunny day in a Vacaville garden.

So here's this praying mantis, a female Mantis religiosa, tucked beneath a Mexican sunflower, Tithonia rotundifola, in a Vacaville garden. She's as still as a stone, and you know how still stones are. Along comes a honey bee, Apis mellifera. She's packing a load of orange pollen.

Holiday? What holiday? It's Labor Day, but honey bees aren't relaxing. They're out in force collecting nectar, pollen, water and propolis.

There aren't that many nematologists who can say their career spans 64 years. UC Davis Distinguished Professor Emeritus Howard Ferris can.
