Species 



of 

 Larva. 



Diloba C(B-

 phala. 



Method by which rendered 

 conspicuous. 



Yellow, green, and black ; 

 freely exposed on leaves of 

 hawthorn &c. 



Unpleasant 

 attribute. 



? Taste or smell. Proof 

 lies in what follows. 



Results of 



J. Jenner Weir, 



using many species 



of Birds and Lizards. 



Disregarded by all 

 the birds. Expe- 

 riment repeated a 

 second season, 

 when the larva 

 was " examined 

 when moving, but 

 not eaten." 



A. G. Butler, 



using Birds, Lacerta 



viridis, Frogs, and 



Spiders. 



Pygara hu- 

 cephala. 



Yellow, orange, and black ; 

 dowuy ; gregarious ; most 

 conspicuous on oak, elm, 

 lime, birch, &c. 



? Taste or smell. Proof 

 lies in what follows. 



Eaten by Lacerta 

 agilis, but evi- 

 dently disliked 

 and generally 



avoided. 



Oi'gyia an- 

 tiqua. 



Black and pink, with hairy 

 tufts ; freely exposed on 

 upper sides of leaves of 

 nearly all garden plants. 



Eversible dorsal glands 

 doubtless yielding 

 odoriferous secre- 

 tion. Hairs also ap- 

 parently disliked, and 

 perhaps irritating. 



Disregarded by all 

 the birds. 



A young Missel- 

 Thrush reared 

 from the nest lias 

 frequently e-aten 

 the larva, but tlie 

 long hairs were 

 always rubbed off 

 before swallowing. 



Porthe^ia 

 auriflua. 



Black, red, and white ; hairy; Eversible dorsal glands: 



very conspicuous on upper secretion volatile and 



sides of leaves of hawthorn irritant. Hairs in- 



&c. tensely irritating. 



Disregarded by all 

 the birds. E.xpe- 

 rinient repeated a 

 second season. 

 Refused by all the 

 Lizards. 



Eaten, without hesi- 

 tation, by a youiig 

 Sky-Lark, whicli, 

 however, died soon 

 afterwards with 

 symptoms whicli 

 may ha\ e been due 

 to irritation from 

 the hairs.

Lasioeampa 

 (Veiidroli-

" Variegated with red, brown, 

 grey, and white, with two 

 blue fascicC near the head, 

 spotted at the sicies with 

 red ; it is tufted with hairs, 

 one thicker than the rest 

 near the tail." Apparently 

 conspicuous on its food- 

 plant — pine. ( Wcithiwod and 

 Humphreys, 'British Moths') 



Curtis states that 

 Walker found the 

 hairs intensely irri- 

 tating on handling 

 the larva.
