PRACTICAL HINTS RELATING TO THE EUPITHECIIDS.

October, and seems to be a general feeder, having been recorded from 

 hawthorn, currant, dogwood, and snowberry, feeding on the leaves. 



The imago of Eupithecia exu/nata is on the wing in May and June, 

 resting by day on the trunks and branches of hawthorn and other trees, 

 posts, fences, and, if disturbed, flies away quickly and often escapes. At 

 dusk it is on the wing naturally, and may sometimes be netted flying 

 round trees, or along hedgesides, but, although widely distributed, never 

 seems to be very abundant. 



The larva of Eupithecia sobrinata is to be beaten from juniper bushes 

 throughout the spring, April and May, clinging tightly to its foodplant, 

 and wanting considerable force to dislodge it. 



The imago of Eupithecia sobrinata flies about the juniper bushes in 

 bright sunshine, or rests thereon so lightly that it is most easily 

 disturbed. Its natural time of flight, however, is at late dusk, when 

 it is sometimes very abundant. The small light Scotch examples which 

 are found by searching the stems of the juniper bushes in Perthshire, 

 etc., are very beautiful, and another supposed local form, also light, but 

 of full size, is to be disturbed from the juniper bushes growing near the 

 cliffs at Dover. It is on the wing from late July until October in one 

 long drawn-out brood. 



The larva of Eupithecia debiliata is to be found in April and May, 

 feeding up between the united leaves of Vaccinium myrtillus. 



The imago of Eupithecia debiliata is on the wing in June and July, 

 when it may be found resting by day on the trunks of trees that grow 

 in the vicinity of its foodplant, from which it may be disturbed by 

 means of the beating-stick. It flies naturally at dusk, and in its local 

 haunts may sometimes be taken in abundance. 



The variable larva of Eupithecia coronata is to be found in June 

 and July, a partial second-brood from August till November, on flowers 

 of Clematis vitalha, Solidago viryaurea, Eupatorium cannabinum, and 

 many other plants. 



The imago of Eupithecia coronata is to be found from April to 

 June, and again as a partial second-brood in August, resting by day on 

 tree-trunks in the neighbourhood of Clematis, etc., or hiding in the 

 thick bushes near, when it may be dislodged by the beating- stick. At 

 dusk it may be taken flying about bushes and hedges over which 

 Clematis is growing. 



The larva of Eupithecia rectam/ulata is to be found in April and 

 May, in the blossoms of apple (wild and cultivated), drawing the petals 

 together and feeding inside the tent thus formed. It may sometimes be 

 collected in large numbers in orchards. 



The imago of Eupithecia rectamjulata is to be found by day in June, 

 resting on the trunks of apple-trees, or on fences or other suitable 

 places in their vicinity. At dusk the moths fly very freely, sometimes 

 in little swarms around the ends of the branches of the apple-trees, 

 when they may be easily netted. 



The larva of Eupithecia pumilata is to be found from May-June, 

 July and September, probably as three broods, on the blossoms of furze, 

 hawthorn, mountain-ash, holly, clematis, etc. 



The imago of Eupithecia pumilata is to be found in April, May- 

 June, and again in July-August, and may be disturbed by day from 

 among its hiding-places by means of the beating-stick, or it may be
