During the sphex's inspection of the nest an experimenter can move the prey a few inches away from the opening of the nest.
After dragging the prey back to the opening of the nest, once again the sphex is compelled to inspect the nest, so the prey is again dropped and left outside during another stereotypical inspection of the nest.
In SpHEX, this is the carboxylate of Asp-313, and it has been shown to form a lateral 2.6-Å hydrogen-bonding interaction with N2 of the bound cyclic intermediate analogue NAG-thiazoline (18).
Inhibition of SpHEX-catalyzed hydrolysis of pNPGlcNAc by GalNAc-isofagomine (3, Fig.
SpHEX is a 506-amino acid protein that adopts a two-domain fold (18).
He used his trick on the head of every dead or wounded sphex, except those he'd killed with it, lifting up their heads for his pile-driver-like blows from two directions at once, as if to show Sourdough how it was done.
Sphexes and robots would have ignored each other, and sphexes would have made straight for the men, who'd have had less than four seconds in which to discover for themselves that they were attacked, prepare to defend themselves, and kill the eight sphexes.
Presently the bears were not needed, because the scorched corpses of sphexes drew live ones from all parts of the plateau even in the absence of noticeable breezes.

Her prey is an adult, medium-sized Acridian (1), such as the White-banded Sphex pursues.
Gripped by the antennae, according to the ritual of the Sphex, the victim is trailed along on foot and laid beside the nest, with the head pointing towards the opening.
Like the Yellow-winged Sphex, whom I have teased so often during her cellaring-operations, she is a narrow conservative, learning nothing and forgetting nothing.
Sphex fly (Zo["o]l.), any one of numerous species of small dipterous flies of the genus Conops and allied genera.
The form of the body is similar to that of a sphex.

A sphex (a kind of wasp) will, in the process of building a nest, dig a burrow, find an insect and sting it, drag it to the burrow, enter the burrow again to inspect the nest, drag the insect inside, and lay its eggs.
The sphex now drags the insect to the burrow, and is compelled to re-enter the burrow to inspect the nest _again_, even though it has just checked.
It is interesting to discover lifeforms as large as a sphex or dung beetle that don’t have the capability of learning, of going beyond its genetically programmed behavior.

When these were cut off close to the head, the Sphex seized the palpi; but when these were likewise cut off, the attempt to drag its prey into the burrow was given up in despair.
The Sphex had not intelligence enough to seize one of the six legs or the ovipositor of the grasshopper, which, as M. Fabre remarks, would have served equally well.
So again, if the paralysed prey with an egg attached to it be taken out of the cell, the Sphex after entering and finding the cell empty, nevertheless closes it up in the usual elaborate manner.
On this account, then, creativity comes in degrees and consists in the ability to monitor one's lower level activities so that when a behavior becames unproductive, one does not continually repeat it, but "recognizes" its futility and tries something new, something "creative".
When the time comes for egg laying, the waspSphex builds a burrow for the purpose and seeks out a cricket which she stings in such a way as to paralyze but not kill it.
She drags the cricket into the burrow, lays her eggs alongside, closes the burrow, then flies away, never to return.

Each Sphex is stupidly limited to an unvarying diet; she hunts only one kind of prey, though her larva accepts them all.
Let us suppose that the Sphex of antiquity, a novice in the gastronomic art, prepared her potted meats with a single kind of game, no matter what.
It was then her descendants who, subdivided into groups and constituted into so many distinct species by the slow travail of the centuries, realized that in addition to the ancestral fare there existed a host of other foods.
