long spiny legs, long slender feelers, and the head bent 

 down so that the mouth comes almost between the 

 front legs. Some are winged and some are not; but 

 even the winged species do not as a rule fly readily and

 smaller species, climbs readily, and favors drier places. 

 It is much bolder than the oriental species, and is not 

 infrequently seen during the day.
