The British Butterflies Described 



curious sharp-looking little chrysalis may be found 

 hung up to some dead stem during winter. 



The butterfly appears in early June and does not 

 generally survive that month. 



THE WOOD WHITE BUTTERFLY (Lcucophasia 

 sinapis), Plate I., Fig. 8. This is the smallest and 

 most fragile of our white butterflies. The wings are 

 white with a black tip on the fore-wing, and the under 

 side of the hind-wing clouded with black scales. The 

 body is long, slender, and a little flattened laterally. 

 It is not a common species, and is very local where it 

 does occur. It has been found as far north as the 

 Lake District, and down to the south coast." It is 

 unrecorded for Scotland, but has been taken in Ireland. 



The caterpillar is green, with yellow lines on the 

 sides ; it feeds on various members of the pea family 

 Vetch, Trefoil, etc. It appears on the wing in May, 

 and sometimes a second brood occurs in August ; so 

 you may look for the caterpillar in June and again in 

 September. 



THE PALE CLOUDED YELLOW BUTTERFLY (Colias 

 Hyale), Plate I., Fig. 9. 1 think there can be little 

 doubt that this fine butterfly is on the increase with us ; 

 from all over the southern counties come records of 

 its comparative plenty. In the Entomologist (October, 

 1911) I read of over one hundred being seen or 

 captured by various collectors. Norfolk, Suffolk, 

 Essex, Kent, Bucks, are amongst the favoured places, 

 and Lucerne- or Clover-fields are the attractions.
