358 . MAINE AGRICULTURAL EXPERIMENT STATION. I908. 



Ogdoconta cinereola. 



Bean Worm. Lot 231. This is a slender naked green cater- 

 pillar, pale with darker longitudinal stripes, measuring when full 

 fed a little more than an inch in length. It was troublesome 

 over the greater part of the State on beans this year, in many 

 cases stripping the vines bare of foliage and pods. At the 

 slightest touch they give a series of violent jerks landing on the 

 ground. Their contortions are laughable even when their 

 depredations are serious. Their habit of jerking off from the 

 plant would seem to make killing them upon the ground prac- 

 tical, or in gardens to which hens have access merely shaking 

 the infested vines for the benefit of the hens might prove a suffi- 

 cient remedy. \\^ith shell-beans arsenical sprays would be 

 practicable. 



Alcothoe caiidata. 



Clear winged moths (Lot 322) were common flying about 

 blossoms of Virgin's Bower (Clematis virginiana) , August 3, 

 1908, at jNIercer, ]\Iaine. The moths were mating at that date. 

 The larva? of this species bore in the stems of clematis. 



Bstigrnene acraea and Diacrisia (Spilosoina) virginica. 

 The hairy "yellow bear" caterpillar of these two species were 

 overwhelmingly troublesome in vegetable and flower gardens 

 all through the State this year. 



Basilona hnperialis. 

 The Imperial IMoth. Lots 329 and 379. Two full fed larv^ 

 of this moth were received this season on white pine, the one 

 from Naples, Alaine, August 11, being the bright yellowish 

 green variety, and the one from North Berwick, August 15, 

 being dark brown. See Figure 51. 



Lapara hoinhycoidcs. 

 Pine Hawk Moth. Lot 315. Several larvae of this moth 

 were received on white pine. This striking caterpillar is par- 

 ticularly inconspicuous in its natural habitat, as when it lies 

 longitudinally along the pine needles — its normal attitude — the 

 green stripes have so much the appearance of the needles that 

 the insect is not noticeable. See Figure 52.
