This helps to keep them warm, and means that they can search for food when other insects are feeling the cold. A bumblebee's bright colours warn off birds and other animals who might want to eat them. Like many insects, bumblebees have special eyes called 'compound eyes'. Compound eyes are made up of many small units and each unit sees part of the bee's surroundings. These 'parts' make up a full 'mosaic' picture in the bee's brain.
Bumblebees see a different wavelength of light to humans, known as UV light.
This means that they are attracted to flowers of certain colours, particularly blue and violet. A compound eye means the bumblebee can detect movement and contrast better than details. Veins that keep the wings stiff run through them. But, bumblebees have very strong thorax muscles allowing them to beat their wings incredibly fast. Sting Bumblebees will only sting when they feel they are in danger.
