The Insular Mole, or East Asian Mole, is a typical example of the genus
Mogera, of which nine species are now recognised and which
occur predominantly in parts of China and Japan. This is the only species
in the genus whose range extends into Southeast Asia proper.
Typically this is a lowland species, thriving in areas of rich, fertile soil. In
Taiwan it reportedly inhabits a variety of undisturbed and disturbed
habitats ranging from forests and riverbanks to fruit farms and other
cultivated areas. However, in mainland China it also occurs in hilly and
mountainous regions.
This mole exhibits the external characteristics typical of Old World moles,
with large front feet (turned sideways for digging), powerful claws, a
short bare snout and a short tail. The smooth, velvet-like fur is
greyish-brown across the entire body.
Moles typically excavate tunnels in firm soil, with the waste soil being
extruded as molehills. Though their eyes are much reduced and their ears
are small, their sensitive snout can easily detect the presence of
earthworms, their main prey, as they patrol their burrows. In addition to soft-bodied invertebrates this
species also consumes insects and insect larvae.
Some moles have a chemical compound in their saliva which can paralyse earthworms and other
invertebrates, thus they can hoard their food prey for later
consumption.
Moles are sometimes perceived as agricultural pests, however their
tunnelling serves to loosen deeper layers of compacted soil, thereby
improving drainage, and bringing rich nutrients to the surface.
The Insular Mole occurs in many provinces of
southern and south-eastern China, as well as the islands of Taiwan (where
it was first described) and Hainan. In 2009 it was reported as resident in
northern Vietnam.

Encounters with moles at surface are uncommon. The specimen in these
three images (above),
tentatively identified as an Insular Mole based on external characters,
was seen on the slopes of Huanggang Shan in the Wuyi Shan mountain range,
Fujian Province, China. Photos thanks to Timothy and Gloria Pwee.
