Norfolk Lepidopterological Notes. 



By (Eev.) a. M. moss, M.A. 

 Though the butterflies of Switzerland rather take the shine out of 

 ours at home — and I hope soon to be able to contribute another July 

 holiday record — yet a few more notes from the eastern counties of 

 England, on the season of 1905, may not be unacceptable. 



Diligent examination of the sallows in Foxley wood, in the spring, 

 resulted in one small larva of Apatura iris, on May 4th. The search 

 was repeated on several occasions, but without avail. The species 

 here appears to be particularly local and difficult to acquire, as the 

 sallows are mainly large bushes, hopelessly interwoven with thick 

 undergrowth of every description as a covert for game. My solitary 

 find, however, was watched with unceasing care and much interest. 

 Its growth was slow, and after moulting on May 9th, and again at the 

 end of the month, it pupated satisfactorily on June 18th, producing a 

 fine female on July 4th. I was particularly struck with the sudden- 

 ness of its emergence, for, although on the morning of that day the 

 pupa looked only slightly more opaque than before, by the evening the 

 butterfly was out. 



In May, the larvae of Apcunea opJiioriravtma occurred commonly 



in the stems of the white striped grass growing in the gardens of this 



city. A visit to Chippenham fen resulted in ten larvae of Plasia 



oriclialcea and one Lencania straminea. During the first half of June 



"■jhe larvEe of HylopMla quercana were common on oak-trees near 



"Norwich ; they are delicate creatures, and are much better found by 



urning up boughs than by beating. A few larvfe of Notodonta trepida, 



^ chaonia, Ci/tnatophora dilnta, Asphalia ridens and A. jiavicornis 



ere taken ; also half a dozen pupa? of (Jymatophora oculana spun up 



5 the roots of poplar. Two specimens of Arctia villica were noted at 



iddon, some dozen miles southeast of Norwich, and a few imagines 



cDrepana hcunula and D. uni/uicida were netted at Horsford. Night 



arching on the heather in Felthorpe woods produced a good stock of 



ti larvae of A(/rotis a(jathina. Disease, however, spread among them 



al carried them ofi' when fullfed, with the exception of some seven or 



eat, which managed to pupate, and have since emerged. Other 



l&ae taken at the same time were Triphaena ianthina, T. fimbria, T. 



itrjecta, T. orhona, Xoctua hrannea, N. festiva, N. caatanea, N. 



xthographa, Boannia repandata, B. rhomboidaria and K}iin('phele 



tixnus. 



lecent additions have been made in the shape of four nearly full- 

 grn larvae of Stauropua fagi, two found on small oak-trees at Strat- 

 toand two on beech at Attlebridge ; and an abundance of Cochlidiun 

 limdca {teatudo) larva3 on oak and beech, at Horsford. These were 

 nobeaten, but very easily procured by turning over the lower 

 brehes of trees and bushes. Three empty cocoons of Sarrothripa 

 revma were taken at the same time, and a few larvje of Karyinene 

 dolnria and Ephyra punctaria and E. trilinearia. Phalera bucephala 

 seei to be more than usually abundant in the district this autumn,
