1961) on conservation work carried out by local naturalists on the Distillery Pond in Colchester in
1956. and the major changes in the flora and fauna of the pond subsequent to the draining and
dredging of the connected Bourne Pond in 1957. Although Richardson does not mention the
Odonata fauna, his report is of interest in view of records held by the Colchester Museum which
give A. juncea. C. splendens, C. puella. C. boltonii and E. cyathigerum as occurring on the pond
between 1953-58. A. juncea and C. boltonii seem to be especially unlikely, and in view of the absence
of any further data, specimens, or even the recorder's name, it is impossible to view the records with
anything other than scepticism. Also in the north-east, the newly established gravel-pit reserve of
the Essex Naturalists 'Trust at Fingringhoe Wick was the subject of some survey work by members
of the C.N.H.S. The Report for 1962 and 1963 contains another piece by Richardson, in which he
gives A. cyanea and L. depressa as species occurring at the Wick.
In all. at least some dragonfly records had been obtained from approximately thirty-six out of a
possible fifty-seven 10 km. squares in Essex by the end of 1979 (Fig. B:4). A summary of Essex
dragonfly records from the early 19th century to the present day is given in Table B:6. and for
Epping Forest in Table B:5.
