warm weather sets in in April, and the sight of any of these may 

 be looked upon as an indication of approaching summer. These 

 twelve are — 



The Swallow-tail (a local species, only to be found in the 

 fenny districts of Cambridgeshire, &c.) 



The Clouded Yellow 



Six of our se^•en White Butterflies, including the Orange 

 Tip 



The Duke of Burgundy Fritillary {Xempobius Lucina) 



The Green Hair-Streak {Thecla riihi) 



One of the Blues {Argiolus) 



One Skipper (Alveolus) 



But by far the greater number of our Butterflies pass the winter 

 in the larva state, about thirty-eight doing so : some are quite 

 small larvaj during the winter, and have to feed up in the spring ; 

 others are nearly full grown, and change to pupte at the approach 

 of spring, so that their appearance in the perfect state varies from 

 May to August. The list of these includes — 



The Pale Clouded YeUow. The Black- Veined Wliite. 

 All the Browns, which form the sub-family Satijridi (one of 

 the Browns, it must be borne in mind, is the Marbled 

 White). 

 The White Admiral. The Purple Emperor. 



Three of our four large Fritillaries. 

 Our five small Fritillaries. The Small Copper. 

 All our Blues, except Argiolus (already noticed as wintering 

 in the pupa state) and JEgon, which winters in the Qgg 

 state. 

 All our Skippers, except Alveolus, which passes the winter as 

 pupa. 



Lastly, we come to the six species which pass the ^^^nter in the 

 egg state. These are — 



One of the Fritillaries {Argynnis Adippe) 

 Four out of our five Hair-Streaks 

 One of our Blues, jfEgoa 



It will thus be seen that, in direct opposition to what we might 

 have expected, more species are in the perfect slate than in the &gg
