The winter is passed in the adult stage beneath fallen leaves, weeds, and 
trash. The adult female (fig. 121) is about one-sixtieth of an inch long, varies 
in color from a russet green to almost black, but is usually dark red, and is 
generally marked with two large, dark spots on each side 
of the body. The male is smaller and is russet salmon, 
with the lateral spots less conspicuous than in the other 
sex. The eggs are globular and when freshly laid are 
clear, gradually turning opaque and later a dark straw 
color. The newly hatehed mite is round, colorless, with 
six legs, and is about the same size as the minute egg, 
which is about one two hundred and fiftieth of an inch in 
diameter. The mites spin a very fine web over the leaf 
and feed under this protection. There are several gen- 
erations during the season. 
Dusting the trees with a mixture of 50 per cent sulphur 
and 50 per cent hydrated lime is recommended for con- 
trolling the red spider, as is also spraying with summer- 
strength lime-sulphur wash. 
CLOVER MITE.” 
~ 
The clover mite, known also as the brown mite. is 
very small, scarcely as large as a pinhead, reddish or 
brownish, and readily recognized under a hand lens 
by its unusually long front legs 
(fig. 122). In the Middle West 
and the Eastern States this mite 
as of importance principally on 
eecount of its damage to clover 
and various grasses, its injuries 
to fruit trees not, as a rule, at- 
tracting attention except during 
periods of drought. It is, how- 
ever, sometimes complained of 
by householders. since during 
the fall the mites may enter 
dwellings, often in large num- 
bers, and become a decided nui- 
sanee. Inthe more arid sections 
of the country, particularly west 
of the Rocky Mountains, the 
«lover mite becomes one of the 
important orchard pests attack- 
ing most stone and pome fruits. 
Badly infested foliage assumes 
a yellowish, sickly appearance 
due to the injuries of the mites, 
and by midsummer or early fall 
much of it may drop to the 
ground. In the East such injury
