Eumeces fasciatus
McIlhenny (1937:232) has published a remarkable account of observations
on the foraging behavior of a large adult male skink (stated to be _E.
fasciatus_ but almost certainly _E. laticeps_) in southern Louisiana,
which climbed among vines on the side of a house and attacked nests of
wasps, _Polistes pallipes_ and _P. bellicosus_, shaking out the larvae,
pausing to crush and swallow the few adults that lit on it and
attempted, unsuccessfully, to sting. After many larvae had been shaken
to the ground the skink descended and made a leisurely search, eating
them in seemingly prodigious quantities. Several times it climbed back
into the vines to shake out more larvae, and each time retrieved from
the ground those it could find. After feeding to repletion it returned
to its habitual shelter in a hollow live oak fifty feet from the house.
In a two-week period, however, it returned frequently to raid the wasp
nests in the vines, and eventually it had attacked all of the 32 nests
that were originally present, completely destroying many of them.
In the course of the present study direct observations on the food
habits of skinks rarely could be made in the field. Most of those seen
had been alarmed by the presence of the observer, and already had begun
a dash for shelter. Others not sufficiently alarmed to take cover, were
affected by an observer's presence, so that usually they ceased their
normal activities and crouched attempting to conceal themselves or
slithered nervously from one vantage point to another, on the alert for
any sign of danger.
