Strona 31 - Œuothera are tied together by elastic threads, that bit of pollen torn from the anther was attached to others by a band of threads, and the insect, in order to free its mouth from that inconvenient appendage began to use its fore-legs. Raising both together towards its mouth, it seized between them the cordon of threads, and rapidly rubbing them one against the other, much as we do in washing our hands, succeeded in cutting the threads and clearing them from its mouth and legs. Then it raised them...
Strona 32 - Bombylius, the two valves of the proboscis serve no other purpose than to protect and guide the sucking tubes, but in the flies which devour pollen besides this function there is also that of grinding the pollen, for which they have special adaptations, for the margins of the two valves at the point of union are transversely dentate with fine and parallel bands of chitine. Probably the greater or less distance of these bands in different species is related to the different size of the pollen upon...
Strona 31 - ... the other, much as we do in washing our hands, succeeded in cutting the threads and clearing them from its mouth and legs. Then it raised them again, and seized the two valves of the proboscis, thoroughly cleaning them of pollen, and the threads yet adhering to it ; and in about three seconds this work of cleaning was complete. At the same time the valves of the proboscis, by rubbing against each other, had masticated the morsel of pollen, and had conveyed the single granules into the channel...
Strona 31 - Since the pollen granules of (Enothera are tied together by elastic threads, that bit of pollen torn from the anther was attached to others by a band of threads, and the insect, in order to free its mouth from that inconvenient appendage began to use its fore-legs. Raising both together towards its mouth, it seized between them the cordon of threads, and rapidly rubbing them one against the other, much as we do in washing our hands, succeeded in cutting the threads and clearing them from its mouth...
Strona 31 - This chewipg of pollen alternates with sucking honey if the flowers have any, and I am of the opinion that the singular structure of the proboscis of flies cannot be fully explained without taking into account its double function of sucking honey and eating pollen. In the...
Strona 31 - As to flies, it has been until now generally admitted that they are exclusively destined to fluid nutriment. But in the summer of 1867, I was somewhat surprised while observing in my garden an Eristalis tenax upon a flower of (Enothera media, to discover that it was eating the pollen. Resting upon its middle and hind legs, it thrust out its fleshy proboscis like an arm, seized a morsel of pollen with the two valves which terminate the proboscis, and tore it away from the anther. Since the pollen...
Strona 32 - Entomologist" for January that " Eristalis feeds chiefly on pollen, and most of the Syrphidse follow its example; the common house-fly eats various solids, and masses of these substances may be found in the stomachs of these Diptera undissolved and unaltered after passing through the entire length of the leathery and extensile proboscis.
