Odonata– common damselflies
Coenagrionidae– typical damselfly shaped; hold wings over back and keep body straight out when resting (as opposed to Lestidae that spread wings slightly and let body sag); front wing with M3 vein originating closer to the nodus than arculus; predators in water as nymphs, in air as adults; not strong fliers like dragonflies

backswimmers, dark on bottom light on top
Diptera- tachinid flies
Tachinidae -large family; have calypters, pteropleural and hypopleural bristles; have well-developed post-scutellum; body often very bristly (but there are exceptions); larvae are all parasitoids on other insects, adults take nectar at flowers.
Neuroptera
Myrmeleontidae - body and wings like damselflies, but wings held peaked over back, not as damselflies; antennae long and clubbed; larvae predators that build pits and catch ants, adults mostly do not feed
always with copulation
if no spermatophore always _______
campaniform sensilla
mechanoreceptor, oval dome like, raise or lower as exoskeleoton mechanically strained
apposition eye
for strong light, highest resolution, ommatidium receives light only from its own lens system
stomatogastric nervous system
innervates stomadaeum and mesenteron (ex - if crop is distended too much, signals sent via this system)
rhabdome
formed from 6-8 retinular cells; nerve impulse initiated here from reaction of photosensitive pigment and light
thoracic endoskeleton
fusion of sternal and pleural apophyses
Coleoptera– blister beetles
Meloidae – elongate beetles with tarsi 5-5-4; claws divided nearly to base so that it looks like there are 4 claws on each tarsus; elytra usually soft and color often gray or black; larvae parasitize bees and wasps by eating young in the nest; adults lay eggs on opening buds and larvae crawl on bees or wasps when they visit; adults eat flowers and leaves.
Neuroptera- green lacewings
Chrysopidae- medium sized; green wings in life (often yellow in dried specimens); eyes golden in life; larvae and adults feed on small insects, especially aphids.
Lepidoptera– tiger moths
Arctiidae bright colored, with spots or stripes (sometimes plain white); shaped like Noctuidae (but these are not generally bright colored); larvae eat plants of many types; adults eat nectar.
Hemiptera- toad bugs
Gelastocoridae - look like little toads in shape and behavior; predators on other insects on the ground
Hymenoptera -ants  http://ant.edb.miyakyo-u.ac.jp/P/PCD0313/A/88.jpg
Formicidae – usually wingless, but winged adults occur regularly; all individuals have an extra constriction between the thorax and abdomen so that there appears to be an extra segment between the two (this is actually the 2nd abdominal segment – some species have a 3rd constriction also); adults feed larvae various things depending on species, some herbivores, some predators, some scavengers, some fungivores; adults eat these things also.
cement layer
protects wax layer, secreted by dermal glands
oviparous
egg laid, dev away from parent, yolk reserves, oviposits eggs, eclosion external
Flight mechanisms: Direct!
each wing movement controlled by contraction: good control and navigation, slower and energy consuming
Aedeagus
male penis, lock + key, to prevent gene flow
Coleoptera - riffle beetles
Elmidae- small aquatic beetles without typical aquatic shape (because they live on bottom and do not swim); usually dark colored with no or few markings; relatively long legs and very short antennae that are usually concealed; larvae and adults eat algae on rocks and logs.
Hemiptera- plant hoppers
Cicadellidae - - very typical looking hoppers; most similar to Cercopidae (spittle bugs), but these have a circle of spines on the hind tibia that the Cicadellidae lack; many are green, but may be brightly colored; feed on phloem of plants as nymphs and adults
accessory pulsatile organs
associated with bases of legs, wings, flaps associated to get blood to extremities
male-female determination
female xx, male xy or x-, some parthenogenetic, viviperous (no males), polyembryony, social insects
Coleoptera - predaceous diving beetles
Gyrinidae - aquatic shape; long, filiform antennae, convex on undersurface; larvae and adults are predators on insects and even small vertebrates
Hymenoptera – solitary wasps
Specidae– look like may other groups of wasps and bees; lack branched hairs of bees and expanded first segment of the hind tarsus that bees have; have a rounded lobe on the side of the pronotum (often with yellow color, but far from always) that does not reach the base of the wing (tegula); other wasps have either no lobe or a pointed extention of the pronotum (which is an inverted U shape on the back – Vespidae)
cerci, styli, caudal filaments, gills
podite derived appendages of abdomen (1st) then other appendages
Orthoptera crickets – crickets
Gryllidae – most are black or brown, but tree crickets are green; have antennae longer than the body; distinguished from katydids (Tettigoniidae) by number of segments on mid-tarsi (Gryllidae – 3; Tettigoniidae – 4); generally scavengers feeding on decaying material, sometimes catch other small insects
light adapted eye (superposition imagery, but apposition phase)
2ndary pigment cells migrage to clear region
Odonata - common skimmers
Libellulidae - dragonflies with no brace vein; anal loop shaped like boot; eyes may or may not touch; wings often (but not always) with pattern; nymphs aquatic predators; adults aerial predators.
pericardial, perivisceral, perineural separated by dorsal (alary muscles) and ventral diaphragm
3 cavities and the 2 divisions of the cross section of the body (cv system)
