Head of the bumblebee; a, antenna; g, tongue used in licking the nectar from flowers; m, maxillae. sugary solution that is formed in the flower by little collections of cells called the nectar glands. The nectar glands are usually so placed that to get to them the insect must first brush the stamens and pistil of the flower. Frequently the location of the necta- ries (nectar glands) is made conspicuous by brightly colored markings on the corolla of the flower. The row of dots seen in the tiger lily is an example. You may easily find other instances of nectar guides, as they are called. Look for them in any of the common fall flowers. Mouth Parts of the Bee. â The mouth of the bee is adapted to take in the foods we have mentioned, and is used for many other purposes for which a more highly developed animal, man, would use the hands and fingers. The honeybee laps or sucks nec- tar from flowers, it chews the pollen, and it uses part of the mouth as a trowel in making the honey- comb. A glance at the figure shows us that the mouth parts of the bee are complex. The parts con- sist of a pair of very small jaws or mandibles, certain other structures, maxillae, part of the lower lip called the labial palps, and a long tonguelike structure called the ligula. Watch a bee on a flower. Try to make out what parts of the mouth are used in taking nectar and in gathering pollen. Make a drawing of the bumblebee, twice natural size, showing as many of the structures we have just described as possible. Label the parts care- fully and put it in your note- book. It will be interesting to compare this drawing with the drawings you make later in the year when you study other insects. You will be surprised to find how much you improve in drawing. Other Insect Visitors. ââ Other insects besides the bee are pollen carriers for flowers. Among the most useful are moths and but- terflies.
