1 14 First Report on Economic Zoology. 
Insects on Osiers and Willows. 
In answer to a request for names of insects observed by Mr. 
Marsh, of Milford School, near Godaiming, who gives instruction in 
Basket-work, and who is growing the different varieties of Willows 
and Osiers with a view of comparing them, and also finding out 
something about their culture and what insects affect them, the 
following reply was sent : — 
As far as one can say from your descriptions of the insects attacking 
your willows and osiers, they are as follows : — 
(1) The Minor Shoulder Knot Moth (Epunda viminalis'). The 
moth appears in July and August, the larva in May ; the pupa is 
subterranean. All the larvae of this genus live exposed and extended 
along the stems of plants. 
(2) The larvae of Syrphidae or Hover Flies ; they are not injurious, 
but beneficial, being Aphis feeders. 
(3) A green Aphis, undoubtedly Siphocoryne capmc, Fabricius. It is 
found on all willows and occurs from April to July. It is fairly common 
round Guildford, Godaiming and that part of Surrey. 
(I) This Aphis is called Melanocanthus salicis, Linn. It is 
especially found on Salix viminalis. The wingless forms appear in April, 
the winged females from the end of June throughout July. It is recorded 
from your district (Guildford) and I have found it in abundance on osiers 
at Wye ; it is also recorded from Kentish Town. 
(5) This Aphis is Ghaitophorus salicivorus , Walker. It varies much 
in hue. They are often seen brick red in colour. 
The osier has a great number of insect pests, especially amongst 
the sawflies, cecids or gall midges, moths and beetles. 
A list of the more important is being prepared. 
Insects on Elm and Willow. 
(Schizoneura lanuginosa , Hartig., and Laclinus viminalis , Fonsc..) 
Specimens of Aphides attacking elm and willow were received 
in October, 1901, from Miss J. Burroughs Norgate, from Enfield. 
One, a large gall on the elm, proved to be the work of an Aphis of 
the same genus as the White Woolly Aphis or American Blight. It 
is known as Schizoneura lanuginosa. The Willow Aphides Laclinus 
viminalis, Fonsc. The correspondent stated that her attention 
was called to this aphis by the number of wasps hovering over a 
lilac bush beneath the willows. They were feeding off the gummy 
honey-dew. The large masses of aphides were then discovered on 
the willow in their typical position. William Curtis noticed that
