THE ESSEX NATURALIST
Pterophoridae
Alucita pentadactyla. Seventeen from June to August; from
Ardleigh, Colchester, Layer Breton, Manningtree, Weeley
and Witham.
N.B.—The list of "micro-moths'' is very incomplete, since we only
had ready means of identification of the two families given
above.
The predominance of Colchester and Weeley in the above list
is due to these being the home bases of the two authors. Many
people assisted us, and we might be permitted to single out for
special mention W. G. Shreeves (Colchester), A. B. Caldicott
(Little Clacton), C. R. Smith (Ardleigh) and P. J. G. Jones
(Halstead).
