Bee Flies as Pollinators

Family Bombyliidae (Bee Flies): A pollinator with a bad reputation. They are among the many flies that imitate bees, bumble bees specifically.

Glamorous Moths #5 – Penstemonia

The way that gardeners feel about moths and butterflies is often quite different, despite how closely related they are.

To What Extent Should We Help Pollinators?

We plant natives, we irrigate and then admire the parade of pollinators in our garden. But we’re also enabling predators like assassin bugs, crab spiders and small milkweed bugs. A shocking number of plants in my garden are homes to predators. It’s painful to observe the latest victims to this insect offense. Should we sitContinue reading “To What Extent Should We Help Pollinators?”
