This handsome bug is quite abundant and widespread, ranging 

 from Canada to Maryland. Its black coat spangled v^ith brovi^n is 

 very distinctive and this in connection v^^ith its size and heavy build 

 separates it from the other Connecticut species. This has also 

 been bred by Hungerford, who finds it has the usual five nymphal 

 instars. The developmental period is about sixty days. Egg 

 laying begins in May.
