The insect order Neuroptera, or net-winged insects, includes the lacewings, mantidflies, antlions, and their relatives.The order consists of some 6,000 species. Thus, superfamily groups fall between order and family while subfamily groups fall between family and genus. An insect name is complete if the genus, species and author names are given because of the rules that govern taxonomy. Morphology . Considered here are some of the more important orders which are likely to be encountered. The dark head  is withdrawn into the thorax but part of it usually is visible. Hind legs modified for jumping = Orthoptera Hind legs not modified for jumping. Usually, they have a relatively flat heads and prominent forward-pointing jaws. Hemiptera / h ɛ ˈ m ɪ p t ər ə / (Latin hemipterus (“half-winged”)) or true bugs are an order of insects comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, bed bugs and shield bugs.They range in size from 1 mm (0.04 in) to around 15 cm (6 in), and share a common arrangement of sucking mouthparts. The mouthparts face forward, helpful when they are in pursuit of prey. They may be found in stored products or natural fibers, such as cotton or wool. Many of these are of minor importance and are studied only from the standpoint of scientific interest. Names of the authors of species follow. Pesticide recommendations in this publication are registered for use in Kentucky, USA ONLY! Their bodies are elongate but slightly flattened, with well-developed legs, antennae, and cerci. Oxygen gets to tissues that need it through their trachea (element 8 in diagram).. No capital letters are used in common names unless they contain a proper noun.

CAUTION! They live in moist, decaying organic matter, especially accumulations of fallen leaves or dead grass. Caterpillars (Order Lepidoptera) are immature stages of butterflies and moths; they have 5 or fewer pairs (Box 1). Neuroptera can be grouped together with the Megaloptera and Raphidioptera in the unranked taxon Neuropterida (once known as Planipennia) including: alderflies, fishflies, dobsonflies, and snakeflies. Grasshoppers' ears … 11 – Crane fly larvae often have fleshy lobes at end of their abdomens. These plant feeders have chewing mouthparts. These names are in parentheses if the classification of the species has changed since it was described. The underside usually is flat while the upper side is rounded, giving them a humpbacked appearance. Each kingdom is then further divided into increasingly smaller groups based on similarities. They often occur in groups on deciduous trees or evergreens. 8 – Drain fly larva have narrow, strap-like plates across the upper surface. (1989). Being able to recognize larval types can tell you a lot about the insect, For example, is it a plant feeder, predator, or a scavenger? Always label specimens with complete collection data in or on each container. The green lacewing, sometimes There are often additional groups used that are intermediate to the groups listed. Look at the abdomen for relatively distinct pairs of fleshy legs. These dingy gray larvae live in decaying organic matter. These are highly specialized larvae; most live in water, soil, wood, or in decaying organic matter. They are good crawlers and resemble small caterpillars but lack a distinct head and legs of any sort. 15 – Fly maggots have no head and a cream to white body that is distinctly tapered at head and blunt at the rear. Tip of abdomen with two leglike appendages, each bearing two claws. Campodeiform larvae may be found in the following insect groups: Coleoptera; Trichoptera; Neuroptera Go to 49; Tiny insects covered with white powder. Many flies have this larval type including blow flies, house flies, and fruit flies. The thorax is wider than the abdomen and many species have a distinct air tube at the end of the abdomen. Some species have distinct, usually dark heads while others do not. They are the immature stages of varies species of gnats. Key to the orders of insects:- adapted from Harold Oldroyd 1958. Neuroptera Lacewings, antlions Holometabolous . Common names are generally in bold letters, although bold insect names in parentheses are not approved common names. Insects develop from egg to adult in a process called metamorphosis which may be generally classified as either gradual or complete. Lacewing, (order Neuroptera), any of a group of insects that are characterized by a complex network of wing veins that give them a lacy appearance. Thorax with 3 pairs of legs, each tipped with a tiny pair of pincers. There is a single fleshy leg at the front and back of  the body. According to the Magazine “Science Teacher” “Understanding dichotomous keys as a means of classification enables students to better comprehend large amounts of information and understand how to organize, compare and contrast, and analyze that information.” Extension   /   Scientific names (genus, species and subspecies) are italicized or underlined with the genus (first) name capitalized. Click for a hub of Extension resources related to the current COVID-19 situation. These predators are active crawlers that hunt prey. The standard groups in a typical complete classification of species are (the example is for a honey bee, Apis mellifera Linnaeus). SECTION 2: Larvae with no segmented thoracic legs. They live in standing, stagnant water, and especially seldom used drains. If it does, you stay on the first section of the key. Dean They are common in compost piles and decaying organic matter. We would like to show you a description here but the site won’t allow us. Many species live in soil feeding on seeds or roots or in decaying wood. Insects belong to a larger group call Arthropoda which includes all animals with segmented legs, segmented bodies and exoskeletons. Help with larval identification is available thru your local Cooperative Extension office. 6-  Midge larvae occur in water or moist organic litter. The femur and tibia may be modified with spines. Go to 14 Insects not like this. Their numbers are nothing short of remarkable — both in terms of how many individual insects there are, as well as how many species of insects there are. Philanthropy & Alumni Larval types with segmented thoracic legs but no fleshy abdominal legs are shown in Boxes 3 and 4. Each of the pictures represents a larval type. Crickets, including katydids, have thin sound-sensitive membranes on their legs. Campodeiform larvae are usually predaceous and typically quite active. Larvae with relatively long thoracic legs and a relatively streamlined, often pointed bodies are shown in Box 3. Start- The first decision along the identification path is whether or not the larva has segmented thoracic legs. Often, insect identification must be based on the larval stage because no adults are present.

A choice is made at each fork that will send you toward an answer. This key is like a path with a series of forks along the way.
