Lab 9 Flashcards
(25 cards)
tagmata
specialized grouping of multiple segments or metameres into a coherently functional morphological units
4 pairs of appendages in the head
antennae, mandibles, first maxillae with paps, second maxillae with labium, and labial palps
sclerites
thicker areas of the cuticle
tergum
Dorsal sclerite
sternum
ventral sclerite
pleuron
lateral sclerite
abdomen
visceral organs; digestion, exertion, reproduction
head
sensory perception, neural integration, food gathering
thorax
locomotion; attachment point for wings and legs
malpigian tubules
excretion
paleopteran
wings held outstretched or upright at rest (dragonflies)
neopteran
wings can fold over the body at rest (flies)
ametabolous
direct development, with immature and adult stages very similar in shape and ecological niche, molting continues beyond sexual maturity
paurometabolous
semi direct development, with partial metamorphosis from immature nymph stage to non-molting adult
hemimetabolous
similar to paurometabolous, but nymphs are aquatic while adults are terrestrial/aerial
holometabolous
complete metamorphosis with 3 different distinct life stages
larva
feeding stage
pupa
transitional / non feeding
adult
reproductive phase
diapause
period of arrested development allowing for insects to avoid adverse environmental condition
alimentary canal
foregut, midgut, handgun (forgot and handgun lined by cuticle)
labial glands
functions as silvery glands; in some insects these are used to secrete self for cocoon production
foregut
pharynx, esophagus, crop, preventriculus, somodeal valve
midgut
primary site of digestion and absorption
