“HAULM fly”; ribbon-footed corn fly. 
—apparently Tipula maculosa. Tlie plants liacl been top-dressed in 
the autumn with nearly rotten horse-manure, and at the time 
of writing were coming through nicely, but about twenty per cent, 
failed, going off after they had first started. The grub was to be 
found with its head well into the heart of the young plant, and the 
leaves all bitten through at the bud. 
On remedies being suggested, operations were at once set on foot, 
by scooping away the soil from every plant; and it was found there 
were often as many as four or five grubs of different size around 
a single plant, at work or about to commence. About half of the 
plants had no grubs at the root, and some that were nearly or quite 
destroyed had only one. 
The hand-picking proved quite successful and did not require 
repeating, as after the first clearing of the grubs not another plant 
was lost. 
Mr. George Brown, writing from Watten Mains, Caithness, 
mentions that the Daddy Longlegs grubs were plentiful in the soil, 
but owing to the rapid start and growth of the corn crop they caused 
no damage.
