Not least, John Clare: From dark green dumps among the dripping grain The lark with sudden impulse starts and sings And mid the smoking rain Quivers her russet wings The "green language" of Clare's poetry calls to mind for Williams something of his Black Mountains upbringing and childhood connection with nature.
We quantified 30 ethograms of completed courtships (Experimental Procedures) in wild-type Oregon-R flies for courtship behaviors including wing fluttering alone (about one-third of total courtship time), abdominal quivering alone (one-seventh of total courtship time), and simultaneous wing fluttering and abdominal quivering (one-seventh of total courtship time).
From jade the eyes turn to topaz as she works herself into a quivering, mental lather over some hypotheticl bird with a broken wing.
They show instead that quivering of the abdomen coincided with female immobility much more than wing fluttering did.
It seems that it does not; a variety of detectors, including insectavox microphones [ 19] (Experimental Procedures), which we used successfully to record the wing song, all failed to detect any air-borne sound associated with quivering (data not shown).
Furthermore, quivering may explain why males of, for example, D. heteroneura, D. melanogaster, and D. silvestris that have amputated wings or an otherwise impaired serenade can still elicit acceptance by the female [ 1, 23 25].
The pair of quivering butterflies in "Papalutzin" are cut from colorful aluminum cans, with the Pepsi logo visible on one blue wing — a monarch reincarnated from industrial waste.
