The male drones mostly look similar to their female counterparts, but in some cases will have more yellow on their sides that extends farther up the back of the thorax. Once she finds a good location underground, the queen will drop her metabolic rate to conserve energy and produce an antifreeze-like chemical to withstand cold temperatures. Close.

Ensuring that your garden beds or potted patio plants provide these resources is another great opportunity for you to help. The signal must be recognizable by the queen and by the workers bees who will eventually assist the queen in incubation and brood-rearing after the first generation is matured.
