Know your native pollinators: Polyester bees

Colletids are one of the smaller bee families in Florida, but are diverse in size and appearance. They’re named for the unique cellophane-like substance that many females secrete to line the walls of their nest cells.

Bloom Report: Wildflowers bloom earlier than normal

Earlier-than-normal blooming of spring wildflowers seems to be occurring more often, but this year stands out because some wildflowers are blooming nearly a month earlier than expected. The influence of this “abnormal” weather will probably be greatest in North Florida. If the National Oceanic and Atmospheric Administration’s (NOAA) climate predictions hold true, March will likely be wetter and warmer than normal, which would speed up the time when mid- or late-spring wildflowers bloom, such as Black-eyed Susan (Rudbeckia hirta) and Blanketflower (Gaillardia pulchella).

Try these alternatives to common invasive species

Some of the plants that are common to our home landscapes are actually invasive species, many of which are now widespread in Florida’s natural areas. Removing these species from your landscape and replacing them with native alternatives can help prevent the spread of invasive species and will provide suitable food and cover for native wildlife. We suggest some “alter-natives” for your landscape.

Know your native pollinators: Bumble bees

Bumble bees are very efficient pollinators because they “buzz pollinate.” The bee grabs onto a flower and vibrates its flight muscles but not its wings. This causes the flower to release its pollen. It also creates an audible buzz at the frequency of a middle C note. The genus name Bombus comes from the Greek bombos, which means “buzzing sound.”

Know your native pollinators: Cuckoo bees

Cuckoo bees are often mistaken for wasps because their body shape resembles a wasp, and they are nearly hairless. They also lack the pollen baskets that most bees have on their legs because they do not collect pollen for their young.

Bloom Report: Early spring brings the blues

A warmer than normal spring is not what many Floridians want to hear as that implies an early start to summer weather. For some relief, think cool, and the cool color of blue spring wildflowers. And by blue, think true blue.
