One of the commonest and most widely distributed species, which is 

 subject to much variation in size and in depth of coloration. Because 

 of the abundance of this species it will be well to indicate the color 

 differences presented by partly grown individuals. These have the 

 sternum yellow with a narrow black stripe each side of middle line, 

 the two converging and uniting in front of posterior margin, and also 

 a row of small black dots along each lateral margin; the legs with 

 numerous annulations which are present on all joints except tarsi, with 

 sometimes indications of a median one on these; cephalothorax and 

 abdomen above nearly as in adults; venter yellow with black dots 

 minute. 



The female L. nidicola builds a shallow excavation or nest under logs 

 and stones along roadsides and in the woods. She hues the nest 

 with silk and often surrounds it with a low rampart of earth or of sticks 

 and leaves. They are frequently met with in these nests with their 

 cocoons in early summer.
