Adaptive Features
of
Insects

Exoskeleton
http://www.backyardnature.net/pix/exoskel1.jpg
Cicada
armour / protection
conserve water
muscle attachment - strength
light weight - flight
Complete Metamorphosis
http://tidcf.nrcan.gc.ca/images/insects/meta_incomp_e.jpg
young & old in different niches -- don't compete
facilitates a dormant state for harsh conditions
Flight
http://www.washington.edu/news/archive/images/20100930_pid60613_aid60611_moth_w400.jpg
flee from threat
leave hostile environment
migration / dispersal / spread
find mate
gather food from large areas
Small Size
http://photos8.org/small_insect_climbing_green_leaf_sjpg1163.jpg
name the insect
short life cycle
can have several generations/year
can exploit many niches
"micro-habitats"
require less food per individual
Adapt Quickly
http://www.bdlive.co.za/incoming/2012/08/01/750499_505389.jpg/ALTERNATES/crop_400x250/750499_505389.jpg
short life cycle allows
quick adaptation ...
1 human generation ~25 years
large reproductive capacity
hundreds of offspring ...
good chance at least a few
will adapt to change
High Reproductive Ability
http://www.biology.ualberta.ca/roland.hp/ftc.jpg
consider:
eggs = 359
sex ratio 1:1
1 egg = 1 larva
mortality = 0
start with 2 individuals ...
after 1 generation ...
pop'n = 359 (duh)
after 4 generations ...
pop'n = 2 billion
can outbreak quickly
can "bounce back" quickly
Dormancy

quiescience: simple & temporary, in response to immediate adverse conditions
diapause: 'arrested development', start/end triggered by env. cues to avoid harsh season
Movement
http://appled.blinkweb.com/uploads.00162585/00186157.jpg
http://www.clipart.dk.co.uk/DKImages/exp_insect/exp_insect098.jpg
spread: local movement
dispersal: movement from
favourable env. to somewhere else
migration: directed movement to
a favourable place

Defenses
behavioral
morphological
chemical
shelter
coloration
jump
fly
motionless
spines
hairs
stingers
repellants / poisons
rely on recognition
bright colours
in tents, duff, nests
inside plant parts:
bark
rolled leaf
gall
camouflage
warning (ladybug, Monarch butterfly)
mimicry (Viceroy Butterfly, clear-wing moths)
deceptive (eye spots)
