Collembola - 🧠ANSWER ✔✔(Springtails)
ametabolous, furcula, retinaculum, collophore, love gardens, FEEDING
behavior: detritivore
Thysanura - 🧠ANSWER ✔✔(silverfish and firebrats) ametabolous -2 cerci,
1 caudal, silk thread fertilization, pests, chewing mouthparts,continue to
,molt after becoming adult, slippery scales, damaging to houses bc they
feed on wallpaper
feeding behavior: detritivore
Ephemeroptera - 🧠ANSWER ✔✔(Mayflies), hemimetabolous; chewing in
nymphs, short adult life, 2-3 caudal tails, NO wing flex, vestigial mouth in
adults, subimago state (only seen in this type), the only type of insect that
molts after having a set of fully functional wings, i. Males die after mating;
females die after laying eggs, emergence swarm; will emerge in unison to
mate, sensitive to water pollution, nymphs have abdominals gills; adults do
not feed; cause traffic hazards, an indicator of water quality, used by
scientists
