Aquatic nymphs Ovipositor lost Plecoptera Terrestrial nymphs Silk glands Embiodea(=Embioptera) No silk glands Zoraptera Dermaptera prognathous head Cerci modified to forceps Cerci not modified Grylloblattodea ? Mantophasmatodea Saltatorial hind legs Orthoptera Hind legs not saltatorial Phasmatodea
3
Hexapod Orders Dermaptera Derma - skin, ptera - wing Number of Species
>1900 Common names earwigs Typical habitats - fossorial - damp, dark Distinguishing characteristics - cerci - large forceps Other features - females show parental care
5
Dermaptera – Life cycle
Female lays eggs in top few cm of soil Hatch in 1 week Female tends eggs & nymphs for 2 weeks Overwinter in soil Mate Mate and complete 1 more cycle
6
Dermaptera - Cerci
7
Hexapod Orders Grylloblattodea Gryllo - cricket, blatto - roach
Number of Species 25 Common names Iceworms, rock crawlers Typical habitats - near melting snow, litter in alpine forests Distinguishing characteristics -multi-segmented cerci -wingless Other features -live in cold habitats -restricted to Northern Hemisphere -omnivorous
8
Grylloblattid - Habitat
10
Grylloblattid – Life cycle
Female lays eggs in soil or moss Hatch in 1 month to 3 years Nymphs – 8 instars (about 7 years) Mate Females sexually mature after 1 year
11
Grylloblattid Distribution
12
Hexapod Orders Mantophasmatodea
Manto - mantid, phasmato - stick insect Number of Species 8 Common names African rock crawlers, gladiators, heelwalkers Typical habitats -xeric, rocky habitat Distinguishing characteristics -wingless -enlarged arolium Other features -closest relative - Grylloblattodea -carnivores
13
Mantophasmatodea - Predatory adaptations
Large eyes Spines on forelegs
14
Eggs hatch - juveniles develop in winter (wet) months
Mantophasmatodea - Life cycle Eggs hatch - juveniles develop in winter (wet) months Autumn rains (May) Mating Eggs laid in egg pod -resists desiccation
15
Mantophasmatodea - Relationship to other orthopteroid orders
Predatory adaptations (mantids) Egg cases (roaches, mantids) Wingless (grylloblattids) Prolonged mating (phasmids) Male eaten after mating (mantids) Substrate communication (stoneflies) Male much smaller than female (mantids)
