Then up to her look-out once more. This time she dropped down to the sand and sunned herself contentedly.
The Bees had long been working. Forward and back they passed unceasingly, now and again one towered, now and again one settled; but never did their labour-song, a droning, buzzing, humming chanty, weaken or gather strength. The Jewel Fly had vanished altogether, yet Spinipes still seemed to fear her coming. A full half hour she stayed on guard, and spent the time in adding to her tower, and rounding off its entrance, which, of its own weight, took a gentle down-curve. Then, after one last gaze upon her egg, she flew afield.
"Good hunting, sister!" said the Ophion Fly. She sat on the same leaf as yesterday.
"I want them now," said Spinipes.
"The're thousands of them, thousands," said the fly, "and most of them quite fat."
It was a flabby, green, black-headed Grub
But Spinipes was too engrossed to hear her. Already, swayed by instinct she was hunting, hunting an unknown quarry in the lucerne. From plant to plant, from leaf to leaf, she fluttered. Now she dropped down to earth, and ran this way and that in the green twilight tangle. Now she sped nimble-footed up a stalk. Now she took flight and skimmed above the leaves.
At last she paused, her every muscle trembling, and stared at what confronted her.
It was a flabby, green, black-headed grub, fixed slug-like on its food-plant. A trail of skeleton tracery marked where its jaws had passed, and, as it reached the border of its leaf it swung its head, and starting near midrib, gnawed yet another ribbon-strip of green.
