ZORAPTERA

Hexapod Orders Zoraptera Zor - pure, aptera - wingless Number of Species 32 Common names None - zorapterans Typical habitats Fossorial - stumps, rotting wood, tropical Distinguishing characteristics -two morphs -winged with eyes -wingless with no eyes Other features -gregarious but no social structure -small (3 mm)

Zoraptera - a potpourri of traits Generalized chewing mouthparts (Orthoptera) Genitalia -asymmetrical (roaches) Reduced Malpighian tubules (hemipteroids) CNS concentrated (hemipteroids) Wing venation reduced (Psocoptera)

Zoraptera - a potpourri of traits Plecoptera Embiodea Zoraptera Dermaptera Grylloblattodea ? Mantophasmatodea Orthoptera Phasmatodea Blattaria Neoptera Isoptera Mantodea Psocoptera Phthiraptera Thysanoptera Hemiptera

EMBIOPTERA (webspinners)

Hexapod Orders Embioptera Embio - lively, ptera - wing Number of Species ≈ 350 Common names webspinners Typical habitats Fossorial - live in subterranean galleries Distinguishing characteristics -foreleg enlarged for silk production Other features legs oriented to run backwards -rarely winged - wings probably dehiscent -communal -show some parental care

Silk producing glands Leg oriented for running backwards
