HEMIPTERA Derived characteristics: piercing, sucking mouthparts (mandibulary and maxillary stylets coadapted, containing alimentary and salivary canals, enclosed in segmented labium)
HEMIPTERA http://www.ento.csiro.au/education/insects/hemiptera.html
Family Rhopalidae (Scentless plant bugs) • some are similar to lygaeids, but can be distinguished through multiple veins in hemielytra • box elder bus (see picture) is a common southern species, feeding on… http://animaldiversity.ummz.umich.edu/site/accounts/pictures/Hemiptera.html
Family Coreidae (leaf-footed bugs) • Scent glands on side of thorax (scents released can be pleasant or not) • some have expanded leaf like hind tibia (hence the name)
Family Cimidae (bed bugs) • ~ 6mm long • Wingless adults; adapted to ectoparasitic life • irritating bites, but unimportant as disease vectors http://animaldiversity.ummz.umich.edu/site/accounts/pictures/Hemiptera.html
Hemiptera with raptorial forelegs - 1 prosternal groove • Family Reduviidae (assassin bugs) • prosternal groove • abdomen widened, exposing lateral margins beyond wings
Family Naucoridae (creeping waterbugs) - hemelytron membrane without venation Hemiptera with raptorial forelegs - 2 • Family Corixidae (water boatmen) • front tarsus scoop-shaped • dark dorsum, light venter
Hemiptera with raptorial forelegs - 3 • Family Belostomatidae (giant waterbugs) • largest hemipterans in US • hemelytron membrane with venation • an easy catch at stadium light in warm nights to which they are attracted An urban legend?
Family Gerridae (waterstriders) • long legged • skate on water surface with middle and hind legs • front legs for food capturing • tarsi clothed with hairs http://animaldiversity.ummz.umich.edu/site/accounts/pictures/Hemiptera.html

HEMIPTERA http://www.ento.csiro.au/education/insects/hemiptera.html
Family Aleyrodidae (whiteflies) • similar to small moths • common pests in greenhouses and • Citrus plants cornicle • Family Aphididae (aphids) • easily recognized by cornicles at the • end of abdomen http://animaldiversity.ummz.umich.edu/site/accounts/pictures/Hemiptera.html
http://www.samford.edu/schools/artsci/biology/invert-03f/pages/101.htmhttp://www.samford.edu/schools/artsci/biology/invert-03f/pages/101.htm • Suborder Coccoidea (scale insects) • females often wing- and legless • males with single wing pair • Family Dactylopiidae - Cochineal Insects • waxy white insects on cacti, exude red dye when squished • economically important before chemical dyes were introduced
THYSANOPTERA • Derived characteristics: • asymmetrical mouthparts with right mandible lost • pretarsus with protrusible "bladder", which balloons out as leg makes contact with the ground. • wing linear with long marginal setae • two or three quiescent, pre-imaginal instars
PSOCOPTERA • Derived characteristics: • large, mobile head, with bulbous postclypeus • membranous wings held roof-like over abdomen
PHTHIRAPTERA • Wingless (apterous) ectoparasites • Three nymphal instars • Hemimetabolous (having a simple metamorphosis, i.e. no pupa) • Mouthparts - mandibles for chewing lice, stylets for sucking lice • Tarsi 1 or 2 segmented (1 in Anoplurans) • Dorsoventally flattened head • Development of operculum in egg • Reduced labial palps • Reduced compound eyes and no ocelli • Antennae are 3 to 5 segmented and capitate • Recessed into the head in the Amblycera • Filiform in the Ischnocera (May be modified as clasping organs in the male) • Typically short in Anoplura
