Blatella bisignata (Brunner) is the most common cockroach of 
the fields. Occurring at all seasons of the year, it does not shun

dead weeds, a number of the roaches exposed by this act will 
rush for shelter. It seems to be more plentiful in the immature 
or flightless state, when its two yellowish brown dorsal stripes 
certainly make it more conspicuous.
