Vor Inbetriebnahme Bitte Lesen,iculty of continuing to ecdyse once the adult had evolved wings. The only Pterygotes which ecdyse in the adult stage are mayflies (Ephemeroptera). Associated with the abolition of ecdysis in other adult Pterygote insects is the loss of ecdysial lines of weakness: thus even though they can be forced
