A goodly number of the Erycinidee, creatures rather fond of shade 
and retirement, but beautiful none the less, ornamented generally with 
white, orange, yellow, or crimson, and often with eye-spots too, rest with 
the wings expanded, and very often, like many moths, on the under- 
surface of leaves. This moth-like habit of resting is well exemplified in 
species of Nymphidium and Eurybia. The richly coloured Diorhina 
and Ancyluris delight to run themselves on the upper surface of leaves, 
selecting for this purpose such leaves as are struck by a strong beam of 
sunlight that finds its way through the green canopy, or such as are on 
the borders of clearings or open spaces. 
Many of the Hesperiidz, or skippers, have a curious way of resting. 
Besides the usual modes of expanding the wings or of closing and elevat- 
ing them, they often rest with the hind-wings but slightly raised above 
the horizontal, while at the same time the fore-wings are held up almost 
perpendicularly. The consequence is that all four wings are plainly 
discernible while the butterflies are at rest. This habit is most fre- 
quently seen among the Pamphilas and their close allies, and is most 
often indulged in when the day is hot, bright. and calm. It is their way 
of sunning themselves, and may be compared to a similar habit that 
exists among carrion-crows, which all have noticed on house-tops or other 
lofty perches, spreading out their sable wings to the brilliant sunshine. 
Moths rest with their wings expanded horizontally at right angles 
or at acute angles with their body, or closed and sloping roof-like over 
their back. In the latter case the hind-w ings venerally partially roll up 
length-wise along their inner border, while the fore-wings lie sloping 
over them. If at rest on leaves they keep usually to the under-surface. 
The gorgeous black and green day-flying Uraniid Cydimon leilus rests 
on the upper surface of leaves, and keeps its wings expanded as though 
to enchant us with their surpassing richness of colour. The Syntomids 
rest generally on the under-surface, and hold their wings fully open or 
at acute angles with the body, while among the Pyralids which also 
generally rest on the under-surface of leaves, both these modes may be 
noticed, in addition to that of keeping them closed roof-like over the 
back. The Geometers, which rest on the upper or on either side of 
leaves, like to keep theirs open, and so do the pretty Hypside, which 
rest on the under-surface. The smaller Noctuids rest on the under 
surface of leaves and keep their wings roof-like. The larger Noctuids, 
such as species of Erebus, Letis, etc., keep their wings expanded hori- 
zontally when at rest. Erebus odora likes to rest head down on tree- 
trunks. Castnia licus, of the family Castniide, sometimes will alight 
on a broad leaf, and spread its wings as though to sun itself. It gen- 
erally, however, elects to sit still with its wings held roof-like. 
Similar ways of holding the wings may be instanced from other 
families of moths. There are, however, certain other interesting and 
even curious details to be observed in particular species. Ancylostomia 
slercorea, the pigeon pea Pyralid, for example, clasping a twig or other
