INSECT TAXONOMIC DIVERSITYBy: Michael Brown
INSECT ORDERS
Ephemeroptera
Odonata
Blattaria
Isoptera
Dermatptera
Orthoptera
Phasmida
Hemiptera
Coleoptera
Lepidoptera
Diptera
Siphonoptera
Hymenoptera
Mantodea
Plecoptea
EPHEMEROPTERAIn complete egg development (egg, nymph, adult)
Immatures are aquatic (naiads)
Unable to fold wings back
Common in freshwater habitats worldwide
ODONATAWhile both dragonflies and damselflies belong to the Odonata and share many common features, then are a number of noticeable differences as well. Even before hatching from the egg, differences in morphology of the egg distinguish dragonflies (Anisoptera) from damselflies (Zygoptera).
BLATTERIACockroaches leave chemical trails in their feces, as well as emitting airborne pheromones for swarming and mating
ISOPTERAHemimetabola
incomplete development (egg, nymph, adult)
Orthopteroid closely related to Blattodea and Mantodea
Distribution: Extremely common in tropical and subtropical climates. Generally less abundant in temperate regions.
DERMATPTERAHemimetabola
incomplete development (egg, nymph, adult)
Orthopteroid closely related to Orthoptera and Phasmatodea
Distribution: Common and widely distributed throughout the world. Largest diversity is found in the tropics and subtropics
ORTHOPTERAFiliform antennae
Hind legs modified for jumping
Front wings thickened and parallel-sided (tegmina
PHASMIDAHemimetabola
incomplete development (egg, nymph, adult)
Orthopteroid closely related to Orthoptera and Dermaptera
Distribution: Common in tropical and subtropical climates where they are found living on their host plants.
HEMIPTERAHemimetabola
incomplete development (egg, nymph, adult)
Hemipteroid closely related to Thysanoptera and Psocoptera
Distribution: Abundant worldwide. All species are terrestrial herbivores.
COLEOPTERAThese beetles are the heaviest of all insects, yet they are strong fliers that buzz loudly when visiting flowers for nectar and pollen. The larvae live in the soil where they feed on roots.
LEPIDOPTERAFront and hind wings with large surface area
Body and wings mostly covered with tiny pigmented scales
DIPTERAOnly one pair of membranous wings present
Hind wings modified as halteres
SIPHONOPTERATeardrop-shaped body bilaterally flattened
Long hind legs adapted for jumping
Heavy bristles (ctenidia) often present on gena and/or pronotum
HYMENOPTERAHolometabola
complete development (egg, larva, pupa, adult)
The Hymenoptera is divided into two suborders:
Symphyta (sawflies and horntails) have a broad junction between thorax and abdomen Apocrita (ants, bees, and wasps) have a narrow junction between the thorax and abdomen.
Distribution: Common worldwide. Third largest order of insects
MANTODEAHemimetabola
incomplete development (egg, nymph, adult)
Orthopteroid closely related to Orthoptera and Blattodea
Distribution: Common in tropical and subtropical climates.
PLECOPTERAHemimetabola
incomplete development (egg, nymph, adult)
Orthopteroid closely related to Orthoptera and Embioptera
Distribution: Common in and around fast-moving streams in temperate and boreal climates.
