11
Q

- terminal segments terminal and sheet like, extending laterally
12
Q
lamellate
A
- leaflike
- terminal segments form oval lobes
13
Q
geniculate
A
- elbowed
- first segment long followed by angled, shorter segments
14
Q
no metamorphosis
A
- insects hatch directly from egg resembling mini adult but lack wings
- molting will result in increase in size
- no major modifications between each molt (ametabolous)
- Thysanura
15
Q
hemimetabolous/ incomplete metamorphosis
A
- young emerge from eggs someone similar to adults but with very large heads
- juvenile stage is a nymph
- development to adult is done through molts
- some nymphs can be aquatic
- Orthoptera, homoptera, isoptera (cockroaches and termites), hemiptera, odonata, plecoptera, and ephemeroptera
16
Q
holometabolous/ complete metamorphosis
A
- egg –> larva –> pupae –> adult
- eggs hatch into segmented worm like larva
- larva feed and grow and undergo many molts
- final molt is into pupal stage which is stationary and non-feeding
- juvenile tissues are reabsorbed and adult organs are formed
- adult emerges from the pupal case
- Coleoptera, diptera, hymenoptera, lepidoptera
