HOP APHIS. 
« 
altogether—of what might be eggs, or broken pellicle of eggs, of some 
insect, but that was all. 
In the course of the present autumn I have carefully examined 
earth from the roots of the Hop mentioned, which had been isolated 
and severely attacked, but have been unable to find any Aphides or 
eggs.— Ed. 
Dead Bines, Leaves, &c. 
With regard to winter harbour of Aphis on the cut bines, dead 
leaves, or in bark or Hop hills, I can state that I received a bundle of 
Hop bines from Kingsnorth, Kent, some time previous to November 
29th, 1882, and examined pieces of these minutely, but could not 
detect either eggs or Aphis presence of any kind in any nooks or 
crannies, nor did any develop in spring. 
I also examined the bark of some sets sent me from Detling with¬ 
out finding Aphides or eggs. Some of these leaves I forwarded to 
Mr. Buckton, who examined them, but similarly did not find Aphis 
presence.* 
The following notes show similar results from observations on the 
growing plant early in the year (March 21st or 29tli) and the earth in 
August:— 
“ I have been looking at my Hop hills, but can see nothing ; the 
shoots are about two inches long, and when cut through longways the 
young leaves can be seen quite plainly about the size of peas, but I 
can see nothing at the present like egg or Fly or Aphis.” f—R ichard 
Cooke, The Croft, Detling, Maidstone. 
With regard to the other trees mentioned, as Willow, &c., there is 
this much to be learnt from it, that the state of the weather which is 
favourable to Aphis increase on one kind of tree or bush will probably 
be to another; therefore, if great increase is observed to be going 
forward, Hops should be looked to. But with regard to the special 
Aphides of another tree infesting Hop, I believe there is no trust¬ 
worthy entomological record at present of that being the case. 
* Perhaps to those who are not acquainted with the great value of the opinion 
of Mr. Buckton as to species or method of life of Aphides, I should mention that he 
has devoted many years to the study of their methods of life, and is the greatest 
English—possibly world-wide—authority on their life-histories, and the author of a 
long and elaborate work giving figures of all the English species in their different 
stages. 
f In two or three cases of detailed and very good observation of some small 
insects (supposed to be Hop Aphis in its early stage) being observed going up the 
stems from the ground, I think that the attack was not Aphis, but of the Hop Frog 
Fly. The specimens in one case were noted as so small as to be “ almost imper¬ 
ceptible” ; in another, when forwarded, they proved to be of Frog Fly, “ Jumper ” 
(Euacantlius, scientifically) ; and to a non-entomologist these insects, when in their i 
first stage, would look very much alike. I have therefore not given the notes here.
