W. The Euplexoptera are nocturnal in their habits, 

 and often migrate in the evening in considerable 

 flocks ; they feed on fruits and flowers, and often 

 do great damage in gardens by depriving the petals 

 of dahlias, pinks, and carnations of their symmetry, 

 by their hungry bite, causing the florist to wage 

 against them a war of extermination. The female 

 Earwig sits on her eggs in the manner of a hen, 

 and after the young ones are hatched they follow 

 their mother, who continues to brood over them for 

 many days with true maternal solicitude.
