Mr Grumps Life in Photos

I spotted this little chap on the way to work and snapped a few shots - he gave me a right song and dance, moving from flower to flower. It was only when I reviewed later that I spotted all the pollen he'd collected in his 'basket'

The pollen basket or corbicula is part of the tibia on the hind legs of the four related lineages of apid bees that used to comprise the family Apidae: the honey bees, bumblebees, stingless bees, and orchid bees. The corbicula ("little basket") is a polished concavity surrounded by a fringe of hairs, into which the pollen is placed; most other bees possess a structure called the scopa, which is similar in function, but is a dense mass of branched hairs into which pollen is pressed, with pollen grains held in place in the narrow spaces between the hairs. A honey bee moistens the forelegs with a protruding tongue and brushes the pollen that has collected on head, body and forward appendages to the hind legs. The pollen is transferred to the pollen comb on the hind legs and then combed, pressed, compacted, and transferred to the corbicula on the outside surface of the tibia of the hind legs. A single hair functions as a pin that secures the middle of the pollen load. Honey and/or nectar is used to moisten the dry pollen. The mixing of the pollen with nectar or honey changes the color of the pollen. The color of the pollen can identify the pollen source. (See? Who says Blipping isn't educational?!)

What a busy bee.. (sorry, couldn't resist!)
