THE MOTHS OF THE BRITISH ISLES. 



in nearly all parts of the British Isles where the food plant 

 occurs, and occasionally in localities from which juniper appears 

 to be absent. 



Double-striped Pug {GynmosccHs { Eupithecid) pumilata). 



This species varies a good deal in the tint of the ground 

 colour and the cross markings. Three forms are depicted on 

 Plate 99 : Fig. 8 is a typical male, and Fig. 9 shows a female 



with distinct red bands (ab. 

 rufifasciata^ Haworth) ; both 

 specimens are from Surrey. 

 The greyish example without 

 red markings (Fig, 10) is from 

 Ireland, and approaches ab. 

 tempestivata^ Zeller, in form. 



The caterpilhir ranges in 

 colour from yellowish-green to 

 reddish ; on the back there is 

 a dark-green or blackish line, 

 and often a series of marks of 

 the same colour ; the lines on 

 the sides are yellowish. It 

 feeds chiefly in or on the 

 flowers of furze, broom, holly, 

 clematis, hawthorn, etc., from May to September. There are 

 certainly two broods, possibly more. The specimens of the 

 first, or spring, generation are usually larger in size and more 

 strongly marked than those of the summer brood. 



The moth is most frequent, perhaps, in April, May, July, and 

 August, but it may be met with in either of the months from 

 April to November. Pretty generally distributed over the 

 British Isles, including the Hebrides and the Orkneys.
