Lophyrus
(Pine Sawflies). A genus of Sawflies, the larvae of which feed on Fir, Spruce, Larch, and other conifers. Several species are known to occur in Britain. At times, the larvae do extensive damage, as they are of social habit, and eat away the needles, so that they leave branches, or even whole trees, bare; they may thus destroy entire plantations. They are seldom hurtful in gardens, however, being restricted to conifers, and do not need to be described at length in this work. Owing to their living and feeding in society, their presence is easily detected, and hand-picking will, in almost all cases, be found an effectual remedy, should they attack conifers in gardens or in pleasure grounds.
