| Summary: | The temporal pattern of activity and hunting behavior of the spider
wasp, Pepsis thisbe, from Trans Pecos, Texas are described.
Females exhibited a bimodal pattern with peak periods of hunting
activities occurring between 0800–0959 and 1600–1759 hr. The
lowest levels of activity (1100–1359 hr) occurred when ambient
temperatures exceeded 38℃. Activity declined abruptly after 1800
hr indicating a strong preference for diurnal activity in this species.
The behavioral components of the hunting sequence consist of an
initial approach and antennation of the host, grooming, antennation
and paralyzation followed in some cases by lapping, ovipositiom
burial of the host, and closure of the nest. The time required to
complete the hunting sequence was recorded for both field and laboratory
encounters between a wasp and spider. The amount of time
required by a female wasp to complete the initial approach and
antennation-paralyzation sequences decreased significantly as a
function of increasing encounter experience. The spider is stung
most frequently (>80%) through the intersegmental membrane
between the sternum and coxa of the first leg. Whether or not a
wasp exhibits lapping behavior is determined by the amount of
time spent in flight searching for a host burrow. |
