The insects of this series are the gall-wasps, or gall-flies, and they are largely 

 parasitic upon plants, though many of them, belonging mainly to the Figitidie, 

 are true parasites upon other insects. Some of them are also guests, or inquilines, 

 inhabiting galls formed originally by other species. Hence it is not unusual for 

 one to breed from a large, multicellular gall several species of minute Hymeu- 

 optera the true gall-maker in small numbers, the guests and parasites sometimes 

 in great quantity. The galls are abnormal plant growths produced by the 

 irritation of the minute larva upon the plant tissue, and each species produces 

 its own peculiar gall so that classification is possible from these abnormal 

 growths as readily as from the insects themselves. The grubs do not feed upon 

 the actual gall tissue, but lie in cells in the gall, apparently subsisting upon 

 material secreted from the inner walls. A gall may have only one larval cell 

 and is then unicellular, or it may have a great many and is then multicellular. 



The ovipositor in this series is partly coiled within the abdomen which is
