Why Influx of Caterpillars Linked to Hawks
"When we try to pick out anything by itself, we find it hitched to everything else in the Universe."--John Muir, My First Summer in the Sierra Muir said it well. Muir (1938-1914), the naturalist and conservationist known as "The Father of Our National Parks," was the driving force behind the...

A Lady Beetle and Gulf Fritillary Caterpillars
What's this? A lady beetle, aka ladybug, sharing stories with Gulf Fritillary caterpillars? Well, not likely. The lady beetle (family Coccinellidae) preys mainly on aphids--it can eat about 50 aphids a day or some 5000 aphids in its lifetime. But it will devour other...

The Survivors
Just call them "The Survivors." They made it through the winter: the bitter cold with subfreezing temperatures; the 54-day drought (will it ever rain again?) and the heavy rain that caught us thinking about ark-building. Butterfly expert Art Shapiro, distinguished professor of evolution and...

The Trouble with Late Bloomers
It's rather troubling trying to rear subtropical butterflies, Gulf Fritillaries (Agraulis vanillae), in late autumn. The string of warm sunny days in late November meant plenty of days for Gulf Frits to mate and reproduce. From eggs to larvae to chrysalids to adults--we watched the life...
