-
Batesian mimicry
- mimic = palatable, less common
- model = not palitable
- both in same area w/ same predators
- predator does the selecting
-
Mullerian Mimicry
- Severally species resemble each other, all not palitable
- predators lean from experience and avoid all
- outside influence chooses
-
Wasmannian Mimicry
- mimics in nest
- host is responsible for selection
- usually bast on chemotatic factors not visual
-
Aggressive Mimicry
- mimics something else
- like insect on orchid
- or eye of owl
-
ametabola
Name of little ones:
wing pad
wing development
shape
eye
habitat/food/mouthparts
- Young
- absent
- apteryogota (no wing development)
- like adult
- simple eyes (same)
- similar
-
Paurometabolous
Name of little ones:
wing pad
wing development
shape
eye
habitat/food/mouthparts
- Nymphs
- External wing pads
- Exoteryogota (develop externally)
- like adult
- compound in both
- similar to adults
-
Hemimetabolous
Name of little ones:
wing pad
wing development
shape
eye
habitat/food/mouthparts
- Naiad
- external
- exopterygota
- Different shape
- compound eyes in both
- unlike adult
-
Holometabolous
Name of little ones:
wing pad
wing development
shape
eye
habitat/food/mouthparts
- larvae (various)
- internal wing pads
- endopterygota
- shape is different
- eye is different
- often unlike adults
-
Stadium
- time period between molts
- from a ∆ in environment
- calculated off GDD
-
-
Brain Hormone
- released through the neurosurgery cells
- regulate activity of prothoracic gland
-
Prothoracic gland hormone (ecdysone)
regulates growth and functions in differentiation
-
Corpus allatum Hormone (Juvenile Hormone)
- suppresses activity of Ecdysone
-
Collembola
- Springtails
- glue-bar
- ametabola
- Has a fercula, colophore and tenaculum
- Found in moist places
- feed on fungi, mold, spores, decaying OM
- occasionally a pest of greenhouses and mushroom cellars
-
Thysanura
- Firebrats, brisletails, silverfish
- bristle-tail
- ametabola
- 3 long cerci and covered with scales
- Found in warm, damp places
- feeding primarily on starchy foods
- adults molt after sexual maturity
- live up to 7 years
-
Ephemeroptera
- mayflies
- for a day-wings
- Hemimetabola
- soft body, long cerci, hold legs forward
- nymphs require 1-2 years to develop
- emergence of subimago and imago in great numbers
- adults don't feed
-
Odonata
- dragonflys or damselflies
- tooth (on maxillae)
- Hemimetabola
- damselfly immature have external gills dragonflys have internal
- nymphs and adults are both predacious
- territorial
- lay eggs in water
- immature stage may last from 1-several years
-
Orhoptera
- Grasshoppers, katydids, walking sticks
- straight-wings
- Paurometabolus
- short horned grasshoppers, crickets, cockroaches, mantids, stick/leaf insects
- Most phytophagous few omni/predaceous
- Most overwinter as eggs
