Subcortical beetle pupae need protection because of the presence in northern pine woods of the fly Xylophagus cinctus (Degeer) whose larvae (Fig. 3) do not live up to its name but rather live under bark of fallen pine trees or their branches preying on the pupae and larvae of longhorn and other beetles. Another beetle developing immediately under bark is Pytho depressus (L.), a peculiarly flattened beetle with flattened larvae as an adaptation to living under bark. Before pupating, the Pytho larva makes a really stout 'fence' around itself (Fig. 4), presumably also as protection against the dreaded Xylophagus larva. Longhorn larvae play an important role in the natural recycling of timber. Larvae of Rhagium bifasciatum (F.) are content to live in dead heart wood — not so nutritious as the subcortical layers, but perhaps a safer environment against the predations of Xylophagus. Holes made by emerging adults allow fungal spores to gain access to stumps facilitating recycling of the Fig. 1.
