Hexapod Orders Phasmatodea Phasma - phantom Number of Species 3,000
Common names Stick insects, leaf insects Typical habitats - arboreal, worldwide Distinguishing characteristics no ovipositor no saltatorial hind legs elongated prothorax Other features -some show parthenogenesis -very cryptic -prolonged mating
4
Features of Phasmatodea
Hindlegs not saltatorial Elongate pronotum No ovipositor
5
Reproduction - mating
6
Reproduction - eggs operculum -mimic seed pods

ISOPTERA (termites)
22
Hexapod Orders Isoptera Iso - equal, ptera - wings Number of Species
3,000 Common names Termites, white ants Typical habitats - fossorial, colonial Distinguishing characteristics Sociality Castes Other features -loss of ovipositor
23

Fig. 3. Dorsal view of various castes in Glossotermes oculatus: (A) apterous immature; (B) female apterous neotenic; (C) nymph; and (D)female nymphoid neotenic. Fig. 2. Live individuals of Glossotermes oculatus, exposed after damage to the log housing the colony. S, soldiers; L, larva; other individuals are apterous immatures. Total length of an apterous immature, from mandibles to tip of abdomen, is about 3mm.

How are castes determined?
King Queen stimulates Produce male inhibitor Produce female inhibitor proctodeal feeding proctodeal feeding Male nymph Female nymph Absorbs male inhibitor Passes female inhibitor Absorbs female inhibitor Passes male inhibitor To other worker nymphs via mutual feeding
