Abstract:

Life cycle and biological characteristics of Caryanda macrocercusa（Mao et Ren, 2007）were investigated during 3 years'
indoor feed. Experimental results showed that the species kept one generation per year under indoor conditions in Dali, Yunnan
Province; the duration of hibernating egg laid in the soil was about 235 days averagely; the egg hatched in early-April next year; the
nymph stadiums consisted of 5 instars and lasted for 63 days; the 5th instar emerged in early-June; mating started on the 10th day after
eclosion and spawned 8-12 eggs on the 10th-30th day after mating with the duration of adult life being about 43 days and dying from
mid-June to early-August individually. Caryanda macrocercusa appears to feed on some grass Arthraxon hispidus and Oplismenus
compositus etc. The species with a sample life cycle and clear biological characteristics in principle can be used as a material in
hybridization experiment and bred as an ornamental insect.
