Nearly all acari produce ova : some few are, however, parthenogenetic, and produce living young. The following are the groups of some importance to the farmer and gardener:— (i) Trombididce, the so-called Spinning Mites or Eed-spiders. These are found on the leaves of plants, and constitute the group Tetranychi (fig. 42), which can be told by their small size and usually semi-transparent bodies, sometimes however tinged w

The mites hibernate within the galls, lea4ng them in the spring to form new ones. The galls are at first plump and smooth, but later b
