CICADIDiE. 



Cicada sordidata Say. This is one of the commonest cicadas found 

 here. It is heard singing in the tops of young pine seedHngs, hiding 

 away amid the foliage, during August and September. 



Like all cicadas, the nymphs live underground, sucking the juices 

 from the roots of trees. Upon reaching maturity, they come up to 

 the surface and crawl up the trunk of some nearby shrub or tree where 

 their shed nymphal skins are often found clinging to the trunks. 



Cicadas first make their appearance at Gainesville about the middle 

 of April.
