OPERATIONS FOR APRIL.

situations having been obtained, each forms a small flat white cocoon, which in a few days becomes 
exactly the colour of the branch ; and in August the perfect moths appear. This moth measures 
a quarter of an inch, when the wings are expanded, all four of which are dull white. The second! 
brood are full fed and become pupae at the end of October, and the moths appear on the fol- 
lowing May. 
Microsetia sericiella, or Satin Pigmy Moth, is another leaf miner ; in dry seasons these become 
very prevalent upon China Roses trained against walls ; their mines presenting the appearance oi 
brown spots upon the leaves. The caterpillars scarcely exceed the eighth of an inch in lengtt 
when full grown, are of a dirty brown colour, with a dark head, and go into the pupse state ir 
October, and the perfect moths appear the following June; the colour of this little creature is u 
blackish-brown with a silky gloss, and measures a quarter of an inch when the wings are expanded 
Lozotcenia rosana , or Rose Leaf Roller. — This is a small but very beautiful moth, measuring 
when the wings are expanded, about half an inch. The first pair have a yellow ground, and arc 
closely netted with red, and crossed with three red bands; the lower wings are dull black, and tht 
abdomen corresponds. The eggs are laid about the end of June, and the young caterpillars feec 
upon the leaves and buds until the end of August, when they form small brown shining cocoons 01 
the under sides of the leaves, which they roll up, and tie fast with silken webs. The buds inhabited 
by these caterpillars are easily distinguished, as they are unable to expand, and a small perforatioi 
is discernible on the side. 
Lozotcenia Icevigana , or smooth oblique Bar. — Perhaps no species does more injury to the buds 
than this ; in habits, colour, and size, it greatly resembles the L. rosana. 
Lozotcenia operana , or Great Hook Tip, appears at the same time as X. rosana ; it seldom attacks 
buds, but is a voracious leaf eater. The perfect moth measures, when the wings are expanded 
one inch. The first pair bright red, netted and clouded with rust colour ; and the second pail 
yellow orange shaded with brown. 
Spilonota cynostabella, or Black-cloaked-Moth, is another species very injurious to buds : i 
also ties four or five leaves together and forms within them a thick silken web, where, when ful 
fed, it becomes a pupa, and the perfect insect appears in September ; the expansion of its wings 
is three-quarters of an inch. The first pair are black and white ; second pair, dull black. 
Spilonota aquana, or Brown cloaked Moth, chiefly feeds upon the leaves, and seldom becomes 
sufficiently numerous to do much injury. 
Argyrotoza Bergmanniana, or Silver-arched Moth. — This little creature measures, when tht 
wings are expanded, about half an inch. The first pair are yellow, clouded with copper, anc 
obscurely netted with the same, having four slightly carved streaks of silvery dots ; the seconc 
pair are brown with yellow fringes. This is one of the most plentiful moths we have, being founc 
in every garden, in all parts of the kingdom, during July and August. The caterpillars are browr 
with a black head, and covered thinly with hairs. When the buds begin to unfold themselves, ii 
April and May, the little caterpillars feed voraciously upon them, and effectually destroy th( 
petals ; when disturbed they run backwards, and descend quickly towards the ground, by mean.' 
of a web they spin from their mouths. When about to become pupse, which happens about th< 
end of June, each spins a thick web within the folded leaves, casts off its caterpillar’s skin, anc 
incloses itself in a small brown cocoon ; in this state it remains until the end of July, and ther 
appears in its winged state. The eggs are laid shortly afterwards, at the base of the buds, and i 
not eaten by “ Tits,” and other insectivorous birds, during the succeeding winter, they become 
larvae the following spring. 
Pterophorus rhododactylus, or Rose Plume Moth, is also a great feeder upon the leaves ; this 
is one of the plume-winged species, measuring nearly an inch when the wings are expanded. The 
first pair are yellow, and consist of two plumes ; the second pair are each divided into three 
plumes.
