Invertebrates
Tioxide and its principal ecological consultants, Physalia have studied
the invertebrate populations of the company site and adjacent estuary
for many years. These surveys have covered terrestrial, freshwater
and estuarine environments. The emphasis, however, has been in the
estuary, since this is surveyed regularly as part of Tioxide’s
worldwide biological monitoring programme of the company’s
effluent discharge sites.
 Butterflies
and Moths
The habitats on the Greatham site are generally not those with a high
diversity of butterflies. At least 16 species however, have been recorded
and these are listed in
Table
8.
Moths have been recorded in more detail recently. At least 56 species
have been recorded and these are listed in Table
9. Further
surveys will almost certainly discover new moth species for the site.
Other Insects
All of the other insect orders are almost certainly under recorded
on the Tioxide site. Less than 20 species of terrestrial beetles
have been recorded on the site (Physalia 1997), where as more detailed
studies on land about 500 m south of Tioxide have recorded nearly
160 species of beetles (Jessop 1996).
The only dragonflies recorded from the site are Blue-tailed Damselfly
(Ischnura elegans), Common Blue Damselfly (Enallagma cythigerum) and
the Common Hawker (Sympetrum striolatum). Although the wetlands on
the Tioxide site are not ideal dragonfly habitat it is likely that
other species also occur.
