Legs, antennae, and orders Flashcards
Blattodea
Cockroaches and termites, Dorsoventrally flat, egg cases (ootheca), Hemimetabolous
Coleoptera
Beetles, elytra, Holometabolous
Dermaptera
Earwigs, cerci (appears as pincer-like things on end of abdomen), shortened elytra, Hemimetabolous
Diptera
True flies, two wings with hind wings modified into halteres, Holometabolous
Hemiptera
True Bugs, piercing/sucking mouthparts, hemelytra, Hemimetabolous
Lepidoptera
Butterflies and Moths, sucking mouth parts, Holometabolous
Mantodea
Mantids, raptorial forelegs, also have egg cases (ootheca), Hemimetabolous
Neuroptera
Lacewings Owlflies Antlions Mantidflies, four membranous wings, chewing mouthparts, Holometabolous
Orthoptera
Grasshoppers Katydids Crickets, thickened forewings (tegmina), Hemimetabolous
Phasmida
Stick Insects, Hemimetabolous
Siphonaptera
Fleas, laterally flat, Holometabolous
Mecoptera
Scorpionflies, Long snout, long slender bodies, long wings, Holometabolous
Hymenoptera
Bees Wasps Ants, hindwing smaller than forewing, Holometabolous
Odonata
Dragonflies Damselflies, Hemimetabolous
Ambulatory Legs
Walking
Cursorial
Running, more extended than ambulatory legs
Saltatorial
Jumping, think grasshoppers
Natatorial
Swimming
Fossorial
Digging
Raptorial
Grasping, think mantids
Aristate
Very small, Flies
Capitate
uniform along antennae with prominent club at the end, butterflies
Clavate
the segments become wider towards the tip of the antenna. This may be gradual along its length, or a sudden increase and therefore mainly affecting the last few joints and giving the appearance of a club, A lot of Beetles
Filiform
Each segment is equal in size all along the length, long
Geniculate
90 degree bend in antennae, Ants
Lamellate
the segments towards the end are flattened and plate-like. This gives the appearance of a fan, June and Scarab beetles
Pectinate
The segments are longer on one side. This gives the appearance of a comb, All sections facing the same way, Beetles
Serrate
Saw blade/serrated look, the branches aren’t quite equal, Beetles
Plumose
the segments each have a number of fine thread-like branches. This gives the appearance of a feather, Moths
Setaceous
The antenna tapers gradually from the base to the tip, Dragonflies
