This is a very small mite, which often proves a serious pest to gardeners, especially to those who cultivate plants under glass. Occasionally, in dry weather, it attacks the leaves of the black currant and destroys them. Fig. 366 represents the male of this species, very much enlarged, the mite itself being scarcely visible to the unaided eye; the small dot within the circle at the side of the figure indicates
