i SILVA OF NORTH AMERICA. CELASTRACE. 
The Wahoo, as this plant is familiarly called,’ is said to have been introduced into English gardens 
as early as 1756,’ and it is still often cultivated, especially in the region where it abounds, although its 
fruit and the autumn coloring of its leaves are less beautiful than those of some of the Old World 
Spindle-trees. 
Few insects are recorded as living on Evonymus in America,’ although the different species are 
occasionally disfigured by them. 
1 Evonymus atropurpureus is also known in some parts of the 
country as Spindle-tree and as Arrow-wood.

8 The larva of a small moth, Hyponomeuta euonymedlla, Schop., 
feeds on the leaves of Evonymus atropurpureus in Kentucky (V. T. 
Chambers, Canadian Entomologist, iv. 42.— Bull. Hayden’s U. S. 
Geolog. Surv. iv. 110). The Fall Web-worm, Hyphantria cunea, 
Drury, sometimes destroys the foliage (Bull. No. 10, Div. Entomol. 
Dept. Agric. U. S. 41); and the bark and branches are frequently 
covered by a scale, Lecanium. The leaves are often infested by 
aphids.
