The middle-leg brushes become moist by contact with the foreleg and hind-leg brushes, probably also by touching the mouthparts themselves, and by passing moist pollen backward.
The question naturally arises whether the movements here are the same as when the plant yields but a small amount of pollen which is collected by the mouthparts and anterior legs.
In this manipulation the forelegs gather pollen from the mouthparts and head; the middle legs, from the forelegs and from the thorax; the hind legs, from the middle legs and from the abdomen.
Yet it is also evident that some of the dry pollen is mingled with the moistened material which the mouthparts and forelegs acquire and together with this is transferred to the baskets.
All that remains on the brushes of the middle legs secures moisture from these brushes or from wet pollen which the brushes collect from the mouthparts or forelegs.
The middle leg also at times reaches far forward, stroking down over the foreleg before it is entirely flexed and apparently combing over with its tarsal brush the face and mouthparts themselves.
This exceedingly wet pollen is removed from the mouthparts by the forelegs (fig.
The movements of the legs and of the mouthparts are so rapid and so many members are in action at once that it is impossible for the eye to follow all at the same time.
All of these brushes also transport wet pollen which has come from the mouthparts and thereby acquire additional moisture.
Obviously such accounts do not apply to cases in which all of the pollen is collected by mouthparts and forelegs.
The mouthparts of the bee are also essential to the proper collection of pollen.
When the bee collects from small flowers, or when the supply is not abundant, the mouthparts are chiefly instrumental in obtaining the pollen.
Mouthparts in both series (consisting all told of about 200 specimens) are fairly constant except in the transforming and extremely young specimens.
The indentations at the corners of the mouth in the papillary fringe are more prominent when the mouthparts are less extended.
In tadpoles having fully developed mouthpartsthe tooth-row formula of 2/3 is invariable, but the coloration is highly variable.
Mouthparts complete; limb bud about half as long as thick; other structural features and coloration closely resemble those in stage 25.
Forelimbs erupted; larval mouthparts absent; corner of mouth between nostril and eye; transverse bands present on hind limbs; tail greatly reduced (about 8 mm.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "mouthparts" in a variety of sentences. We hope that you will now be able to make sentences using this word.
