Flying days in February

Posted by blueberrytalk on February 7, 2012

Four warm sunny days in early February have allowed the bees to visit the hazelnut catkins. Some years they never get a chance because of cold weather.

Bees and blueberry pollen

Posted by blueberrytalk on June 24, 2011

The Mason bee (top left) has loaded up with blueberry pollen. The Sweat bee (bottom left) was captured right inside a blueberry blossom and the picture shows a lot of pollen.The honeybee (top right) comes from a colony where bees specialize in productive pollen sources. (It’s hard to gather pollen from blueberries.) The bumblebee comes to the blueberries after gathering pollen elsewhere (bottom right).

Mason bees and pollen

Posted by blueberrytalk on June 12, 2011

Unlike honeybees, Mason bees carry pollen on stiff hairs under the abdomen called “scopa”. The scopa are well positioned to facilitate good pollination. Click on the picture and magnify to see the pollen grains.

The colours of rhododendron pollen

Posted by blueberrytalk on June 11, 2011

Many rhododendrons are in bloom and the bees are all over the rhododendrons so we are assuming that rhododendrons are the pollen source. Click on the picture to enlarge.

Late pussywillow

pussywillow pollenThis pussywillow comes about a month after an earlier pussywillow. By now the dandelions are at their peak so there is not a shortage of pollen. There are a lot of good foraging sources for the bees just prior to blueberry bloom.

hazelnut catkins

A week ago the bees started to bring in a pink-grey pollen from an unknown source. Today, at marginal temperatures for flying, they discovered the yellow pollen on the hazelnut catkins and the hazelnuts were abuzz with bees.

Climbing hydrangea is a favorite bee source of pollen. There is a faint pinkish blush on this light colored pollen.

Dandelions fade as blueberries blossom

Posted by blueberrytalk on April 27, 2010

Blueberry growers have been told that bees will forsake the blueberry blossoms in favour of dandelions. The pictures below tell a different story. On the left the bright orange dandelion pollen shows that the bees have been spending a lot of time in the dandelions. Now that the blueberries are about 10% bloom the picture on the right shows little indication of dandelion activity and most of the dandelions have gone to seed.
