|A distinctive species, Tillus elongatus
is usually found on dead wood where it feeds on the
larvae of another beetle Ptilinus pecticornis.
Described as being local in the UK, the male differs from
the female by being all black, whilst the female has a
red pronutum. This is an active species, with this one
being one of the most difficult to photograph, rarely
staying still enough. The female (found at Wollaton Park
in July 2013) is shown in the top two photographs, being
larger than the male, which was found on a standing dead
Beech trunk at Warsop Wood in June 2010.
