[Ligne directrice - Note] Note du photographe
The blood or hemolymph, as in other arthropods, is carried in an open circulatory system. The body organs, "heart" (dorsal aorta), muscles, etc. are surrounded in a reservoir of blood. The dorsal aorta does pulse blood through its long tube, though, so there is a circulation of sorts.

In fertilised queens the ovaries are activated and when the queen lays her egg it passes along the oviduct to the vagina. In the vagina there is a container called the spermatheca. This is where the queen stored sperm from her mating. Before she lays the egg she will decide whether to use sperm from the spermatheca to fertilise it or not. Non-fertilised eggs grow into males, and only fertilised eggs grow into females and queens.

As in all animals hormones play a big role in the growth and development of the bumblebee. The hormones that stimulate the development of the ovaries are suppressed in the other female worker bees while the queen remains dominant. Salivary glands in the head secrete saliva which is mixed with the nectar and pollen. Saliva is also mixed into the nest materials to soften them. The fat body is a nutritional store; before hibernation queens eat as much as they can to enlarge their fat body, and the fat in the cells is used up during hibernation.

Hi Siegfried,

Very nice and well taken macro shot. I like very much the blurred background that lets the viewer concentrate all his attention on the subject. In my opinion, framing the scene closer to the right would not probably be a bad idea. Excellent shot!

Have a nice WE.
JR

Lovely macro shot and beautiful colours. I think the mottled, soft background works well.
