“ Some so like thorns and Nettles live, 
That none can for them, when they perish, grieve 
but in truth with little justice to this vegetable outcast, for when does it prove the aggressor, 
or engage in active warfare against its neighbour ? To how many little creatures does it 
afford friendly protection and subsistence ; for Entomologists assure us that not less than 
thirty species of insects are nurtured upon the Nettle alone : as Haltica oleracea, semicenea, 
and testacea, Chrysomela Banksii, Vanessa Atalanta , V. Io , V. urticce, V. album , Lipa- 
rus asper, L. elevatus, Chrysomela polita , Apion frumentarium , A. Curculio Mali, Rhyn- 
chcenus Austriacus , Cassida splendidula , Aphis urticata , Tortrix urticaria, and the splen¬ 
did Nymphalis gemmatus , a butterfly, distinguished by its four peacock’s eyes on each 
wing; its caterpillar black dotted with white. Tremella TJrticce fills the furrows of 
the stalks of dead Nettles during the winter months, with orange coloured streaks; and 
JEcidium Urticce , with capsules cylindrical, light reddish brown; seeds pale yellow; grows 
on the under side the leaves, in spring and autumn. Clavaria compressa also may be 
found on the decayed stems, in groups of threes, of an olive colour* changing to black: 
stem short, thick. E.)
