Abstract
Recently
there has been a
growing
interdisciplinary
interest
in
understanding
the
functional
mechanisms
and
evolutionary
origins
of
animal
communication
through
substrate-borne
vibration1,2,3
, but
few
studies
have
successfully
assembled
a
comprehensive
understanding
of
vibrational
communication
within
and
across
a
related
group
. The
genus
Deinacrida
(giant
weta)
is
a
clade
of
nocturnal
,
herbivorous
,
apterous
Orthoptera
belonging
to the
family
Anosostomatidae4
. They are of
Gondwanan
lineage
with
eleven
endemic
species
found
in
New
Zealand
(Fig
.
1a,b)5,6
.
Until
now
, the
primary
mechanism
of
intraspecific
communication
in this
terrestrial
group
remained
a
mystery
. The
purpose
of this
study
was to
test
the
hypothesis
that the
Deinacrida
utilize
substrate-borne
vibrational
signals
in
communication
.
We
look
first
at
D

rugosa
, the
Cook
Strait
giant
weta
(Fig
.

.
We
sought
to:
1)
determine
if the
species
uses
vibrational
signals
, and if
so
2)
describe
how the
signal
is
produced
,
3)
describe
the
bioacoustic
structure
of the
signal
,
4)
test
the
hypothesis
that
vibrational
signaling
is
related
to
social
context
, and
5)
determine
the
function
of the
vibrational
signal
.
