blatta70 Posted February 1, 2009 Share Posted February 1, 2009 Hello, this is Mark. I am interested to know what the main identifying factors between the roach families Blattidae and Blattellidae are. I know that the oothecas from Blattellids tend to house more eggs and are often larger than those of Blattids but are there any physical characteristics in both adults and nymphs that differentiate the two families? Any input will be appreciated. Thanks, Mark Quote Link to comment Share on other sites More sharing options...
