Although insects, as a whole, were not remarkably plentiful, a number 
of interesting species were taken. The most plentiful and noticeable 
on the uplands were the Small Heath butterflies and the upland Skipjack 
beetles. Soldier beetles of various species abounded, and Weevils were 
very numerous. About the streams during the daytime Stoneflies were 
present in swarms, and in the lanes during the evenings Caddis-flies and 
May-flies were flying in enormous numbers. 
Butterflies and Moths were not represented by very many species, 
but the following were listed by Mr. W. E. Wattam : — 
Pieris brassicae L. 
P. rapae L. 
P. napi L. 
Vanessa urticae L. 
Pyrameis atalanta L. 
Caenonympha pamphilus L. 
Chrysophanus phloeas L. 
Abraxas sylvata Scop. 
Fidonia atomaria L. 
Melanippe fluctuata L. 
M . montanata L. 
( Triphaena pronub a L.). 
and larvae of the Oak Eggar moth 
The most interesting of the Coleoptera was Rhagium mordax D.G., 
taken by Mr. Cheetham, and the following were obtained while working 
in other groups : — 
Notiophilus biguttatus F. 
Nebria gyllenhali Sr. 
Agonum ruficornis Gz

Cantharis pellucida F. 
C. palludosa Fn. 
Rhagonycha limbata Th. 
Rhagium mordax D.G. 
Gastroidea polygoni L. 
Blaps mucronata Lt. 
Adult Hemiptera were rather scarce, but immature specimens were 
quite plentiful. Several good species were obtained. Oaks supplied 
Calocoris ochromelas and Cyllocoris flavonotatus in large numbers almost 
wherever this tree occurred, and several specimens of Harpocera thoracica 
were taken. The minute Microphysa pselaphiformis occurred, and in 
the River Dee the small and interesting Micronecta minutissima abounded, 
a species which does not appear to have been recorded for the county 
since 1868. The following species were taken : — 
Heteroptera : 
Velia currens F. 
Gerris lateralis v. costae H.S. 
Microphysa pselaphiformis Curt. 
Pithanus maerkeli H.S.

P. varians H.S. 
Callicorixa praeusta Fieb. 
Micronecta minutissima L.
