Springtime for the Bees

Hives #1-4 after the February 9 blizzard.
It was a harsh winter here in Connecticut, but I had 100% survival on my five beehives from last year, thanks in large part probably due to generous feeding of the colonies last fall. The bees received protein supplements, and were left with whatever honey they had stored over the summer in addition to enough sugar syrup to get the combs good and full of stores.

Skunk Cabbage, Symplocarpus foetidus.

In late February and early March, the Skunk Cabbage provided the first source of natural pollen for the bees. Skunk Cabbage inflorescences heat themselves up by oxidizing stored carbohydrates, possibly to keep pollinators active on chilly days as well as to melt away snow and ice. On sunny days when temperatures were well above freezing, the bees would be out patrolling the local swamps and streamsides, and coming back absolutely covered with pale yellow pollen.

Hive entrance in early May. Note the drones (male bees) peeking out at left.
 A little bit later the Red Maples bloomed, then Sugar and Norway Maples, providing more pollen and some nectar. Right now a lot of excellent nectar plants are flowering. Apple trees, other fruit trees and dandelions are past their peak but still pretty abundant, and Autumn Olive is just starting. The weather has been a little bit cool and cloudy lately, but my strongest hive had already just about filled one medium "super" (upper box for storing honey) with maple and apple nectar, and later this week the weather and flower conditions should be excellent for all the hives to bring in many more pounds of honey.

The bee populations are in good shape, with the queens producing reasonably solid patterns of new brood in all of the hives. There hasn't been any loss of bees to swarming yet, although I did wind up making make two splits from hives that were starting to make new queens, probably in preparation for casting a swarm. I hear that there have been a few swarms from other hives in the area. Varroa mites are the great plague of the modern beekeeper, and while mites are definitely present in all of the hives, mite levels haven't reached the stage where harsh treatments are called for.
