is very common to find the larvae attended by ants of various 
kinds, which run all over them, and the larvae do not notice 
them in the least even when feeding. The pupae also seem to 
attract ants.”

camp ; for the food-plant grows abundantly in the clearing. 
The larvae are found sometimes on the upper side of a leaf 
even during the heat of the day, and they are leaf-green in 
colour. Both larvae and pupae attract ants to a remarkable 
degree. I have learnt that if ants are running about on the 
food-plant without flowers, larvae are almost certainly on it, 
and if there are no ants I do not trouble to make an ex- 
haustive search. My first half-dozen larvae were placed in 
a box covered with fine muslin. On the following morning I 
discovered that our house ants, a different species from those 
on the plants, had eaten a hole in the muslin and were 
swarming over the larvae. I then put two thicknesses of 
muslin over the box, but the ants again ate it through, and 
so now, as they do not seem to hurt the larvae, I do not 
trouble to remove them. ‘The pupae are placed indifferently 
on upper or under side of a leaf and frequently head down- 
wards on a stem, and ants congregate about them during the 
whole period of pupation. The ants work hard in an en- 
deavour apparently to cover up the pupae with débris. They 
heap up little particles of sawdust, larval droppings, etc., 
round pupae on the floor of the box, and some attempt is 
even made to cover the pupae on the side walls. I found to- 
day on the outside of the roof of the box a little collection of 
débris with which ants were busily covering a fissure in the 
wood which led through to a pupa on the inner side of the 
roof. Some larvae have pupated on the floor of the box, but 
this does not affect the wing-development of the butterflies, 
for they always seem to find a suitable position in time. I 
have from time to time lost other butterflies which have not 
been able to develop properly owing to their pupae having 
fallen down. By the way, the larvae are usually green, but
