abstract = {Embioptera (webspinners) are unique among insects in that
juvenile and adults of both sexes spin silk. They possess
spinning apparatuses in the basitarsomeres of their
prothoracic legs, which they use to build galleries as
habitat and protection. Embioptera are primitively social
and cooperate in building the galleries. They also show
sexual dimorphism that comprises modifications of the
mandibles in males, the winglessness of the females and
differences in the morphology of the forelegs. In the
present investigation we address the correlation of spinning
behaviour and sexual dimorphism in the spinning apparatus of
Aposthonia ceylonica (Enderlein, 1912). To analyse spinning
behaviour we conducted video observations of Ap. ceylonica
in artificial habitats. We observed females and males alone
as well as female–male pairs to cover possible effects of
interactions between sexes. The morphology of the spinning
apparatus was analysed and reconstructed using high
resolution X-ray computed tomography (SRμCT). The
observations show that during trials of 24 h adult males and
females produce similar amounts of silk per body weight,
despite the fact that adult males do not feed, perhaps due
to modifications of their mandibles related to courtship
that interfere with feeding. Spinning glands in males are
distinctly smaller than in females in absolute values, which
reflect the general size difference in females and males.
Despite their smaller body size, the volumes of reservoirs
of spinning glands are larger in males in relative as well
as in absolute values. Together with spinning behaviour and
the amount of silk production, this indicates that males
produce and store gland secretions in the large reservoirs
prior to their final moult for later use.},
