Ephemeroptera

Mayflies or shadflies are insects belonging to the order
Ephemeroptera. There wings are membranous,with
extensive venation,and are held upright like those of a
butterfly. The second segment of the thorax, which bears
the forewings, is enlarged, holding the main flight
muscles.
Odonata

This group consist of dragonflies and damselflies. minute antennae,
extremely large eyes (filling most of the head), two pairs of
transparent membranous wings with many small veins, a long
slender abdomen, an aquatic larval stage (nymph) with posterior
tracheal gills, and a prehensile labium (extendible jaws underneath
the head).
Blattaria

A cockroach consist of this group. Cockroaches are long, flat,
brown insects. Their heads point downward and have chewing
mouthparts. A plate from the top of the thorax covers the head
when you look down on them, so you can't actually see the head.
They are very fast runners. They have long antennae, and at the
end of the abdomen are two short antennae-like structures that
sense air current and vibrations.
Isoptera

Isoptera consist of termites. Termites are small to medium sized
insects ranging form 3-20 millimetres in body length. 2 pairs of
membranous wings of equal length. Wings are present in
reproductive castes only and shed after mating. Mandibulate
(chewing) mouthparts.
Dermatptera

This group consists of earwigs. Earwigs are a distinctive group of
insects of small to medium size, ranging from 5 to 50 millimetres in
length. 2 pairs of wings. The forewings are short and protectively
hardened. The hind wings are membranous and folded in a fan-like
way underneath the forewings when not in use.
Orthoptera

This group consists of grasshoppers, crickets, cave crickets,
Jerusalem crickets, katydids, weta, lubber, Acrida, and locusts.
These insects often have a pair of elongated and thickened
forewings and a membranous hind pair.
Phasmida

This group has stick insects, walking sticks or stick-bugs, phasmids,
ghost insects and leaf insects. Stick-insects are found in nearly all
temperate and tropical ecosystems. Undergo an incomplete
metamorphosis, with the young nymphs resembling miniature, albeit
wingless, adults.
Hemiptera

Hemiptera has cicadas, aphids, planthoppers, leafhoppers, shield
bugs. Wings are generally membranous but in some species the
forewings may be hardened at the base. Compound eyes of
various forms.
Coleoptera

The order of insects for this group are beetles, ladybird beetles
(family Coccinellidae), click beetles (Elateridae), scarabs
(Scarabaeidae), and fireflies (Lampyridae). adults of which are as
small as 0.3 mm long, to the giant Goliath and Hercules beetles
(Scarabaeidae), which can be well over 15 cm.
Lepidoptera

This group consists of moths and butterflies. They have a welldeveloped head with chewing mouthparts. In addition to three
pairs of legs on the thorax, they have two to eight pairs of fleshy
abdominal prolegs that are structurally different from the thoracic
legs.
Diptera

This group consist of true flies. Dipterans also have large eyes, and
may have either long antennae (Nematocera) or short antennae
(Brachycera). Feed on blood, and some may transmit vertebrate
diseases.
Siphonoptera

Fleas are the insects forming this group. Adult fleas feed on the
blood of mammals (about 90%) and birds (about 10%). Backwardpointing bristles of the hard cuticle prevent fleas from falling off or
being easily captured by the host.
Hymenoptera

One of the largest orders of insects: sawflies, wasps, bees and ants.

Derived from the Greek words "hymen" meaning membrane and
"ptera" meaning wings.

Mantodea

Group is made of praying mantids. Their large size can range from
10 to 120 millimetres in body length. Very mobile triangular shaped
head with distinctive ocelli.
Plecoptera

Are an order of insects,commonly known as
stoneflies. Elongated, flattened, soft body.
Mandibulate mouthparts and Long legs.
