SLENDER PUG. 245 



The long, thin caterpillar is yellowish green ; a pale olive line 

 along the middle of the back, connecting a series of urn-shaped 

 blotches of the same colour ; two pale olive, irregular lines on 

 each side. It feeds, in June and July, on flowers of stitchvvort 

 {Stellaria holosted). 



The moth is out in May and June, sometimes later; examples 

 of a second brood have been obtained in August and September. 

 It flies in the afternoon, but only when the sun shines, and 

 where the food plant grows freely. 



The species occurs in all the eastern counties of England, in 

 Bucks., and in the northern counties to Cumberland and 

 Northumberland. In Wales it has been recorded from Colwyn, 

 Denbighshire; in Scotland it is widely spread to Perthshire; 

 it is local and scarce in Ireland. 



Slender Pug {Enpitheda temdata). 



The fore wings are rather rounded ; grey, more or less tinged 

 with brownish, and with ochreous or reddish brown along the 

 front edge ; the latter with dusky clouds upon it ; the cross 

 lines are dark grey brown and fairly distinct, and the discal 

 spot is black (Plate 98, Fig. 5). A large grey form from Moray, 

 in Scotland, has been named dtierce^ Gregson. 



Caterpillar, rather stumpy, and dingy yellowish green in 

 colour, the sides and middle of the back rosy ; a series of dusky 

 spots, edged by black lines or short streaks, along the back ; 

 and a row of pinkish oblique stripes on the sides. It feeds, in 

 the spring, in sallow catkins, and the moths may often be bred 

 in numbers, in June and July, from those catkins which fall 

 most readily from the bushes when we go " a sallowing." 

 Moths frequently rest on the stems, and where there is a clump 

 of well-grown sallows, a good series may be obtained. 



The species is partial to fens and marshy places, and is found 

 in such situations over the greater part of the British Isles.
