... pisum ) may drop off their host plant and assume a stereotypic posture that rotates them in midair to land on their feet. The sensory information triggering aphids to assume this posture has so far been unknown. We subjected aphids to a series of tests, isolating the sensory cues experienced during free...

... mechanism and to check for the influence of morphological changes. T. wilhelma displays a unique mode of locomotion among sponges, without reorganizing the whole sponge body. The overall morphology was stable, and skeletal rotation during movement was shown; this is the first time that such movement has...

... the leading edge, whereas the centre of wing mass was about 1 mm, or 30% of the wing chord, behind the leading edge. The calculated values for the relative magnitudes of rotational to flapping velocity are also given in the table. Values range from 0·67 to 0·76 in Eristalis tenax and from 0·66 to 0·86...
