RMRD1KE1–. Elementary entomology. Entomology. Fig. 35S. The pine-cone willow gall caused by a cecidomyiid, cut open at right to show maggots within (After Washburn) Fungus-gnats. Wherever there is decaying vegetable matter or damp fungi, as in decaying wood, under damp bark, in decom- posing leaves, etc., there are found small, white or pink maggots, which develop into the graceful little fungus-gnats {JMycetopJiilidac). The larvae often stick together in large patches, and sometimes form long processions of wriggling maggots. One species feeds on injured apples, while another has been shown to cause a
