The 13 Forms of Insect Antennae
The 13 Forms of Insect Antennae Antennae are movable sensory organs located on the head of most arthropods. All insects have a pair of antennae, but spiders have none. Insect antennae are segmented, and usually located above or between the eyes. How Do Insects Use Antennae? Antennae serve different sensory functions for different insects. In general, the antennae might be used to detect odors and tastes, wind speed and direction, heat and moisture, and even touch. A few insects have auditory insects on their antennae, so theyre involved in hearing.à In some insects, the antennae may even serve a non-sensory function, such as grasping prey. 13 Different Shapes Because antennae serve different functions, their forms vary greatly within the insect world. In all, there are about 13 different antennae shapes, and the form of an insects antennae may be an important key to its identification. Learn to differentiate the forms of insect antennae, and it will help you improve your insect identification skills. Aristate Are Pouch-Like Aristate antennae are pouch-like, with a lateral bristle. Aristate antennae are most notably found in the Diptera (true flies). Capitate Have a Prominent Club or Knob at Their Ends Capitate antennae have a prominent club or knob at their ends. The term capitate derives from the Latin caput, meaning head. Butterflies (Lepidoptera)à often have capitate form antennae. Clavate Have a Gradual Club or Knob The term clavate comes from the Latinà clava, meaning club. Clavate antennae terminate in a gradual club or knob (unlike the capitate antennae, which end with an abrupt, pronounced knob). This antennae form is found most often in beetles, such as in carrion beetles. Filiform Are Slender and Thread-Like The term filiform comes from the Latin filum, meaning thread. Filiform antennae are slender and thread-like in form. Because the segments are of uniform widths, there is no taper to filiform antennae. Examples of insects with filiform antennae include: rock crawlers (order Grylloblattodea)gladiators (order Mantophasmatodea)angel insects (order Zoraptera)cockroaches (order Blattodea) Flabellate Look Like a Folding Paper Fan Flabellateà comes from the Latin flabellum, meaning fan. In flabellate antennae, the terminal segments extend laterally, with long, parallel lobes that lie flat against one another. This feature looks like a folding paper fan. Flabellate (or flabelliform) antennae are found in several insect groups within the Coleoptera, the Hymenoptera, and the Lepidoptera. Geniculate Are Bent or Hinged Sharply Geniculate antennae are bent or hinged sharply, almost like a knee or elbow joint. The term geniculate derives from the Latin genu, meaning knee. Geniculate antennae are found mainly in ants or bees. Lamellate Are Flattened and Nested The term lamellate comes from the Latin lamella, meaning a thin plate or scale. In lamellate antennae, the segments at the tip are flattened and nested, so they look like a folding fan. To see an example of lamellate antennae, look at a scarab beetle. Monofiliform Look Like Strings of Beads Monofiliform comes from the Latin monile, meaning necklace. Moniliform antennae look like strings of beads. The segments are usually spherical, and uniform in size. The termites (order Isoptera) are a good example of insects with moniliform antennae. Pectinate Have a Comb-Like Shape The segments of pectinate antennae are longer on one side, giving each antennae a comb-like shape. Bipectinate antennae look like two-sided combs. The term pectinate derives from the Latin pectin, meaning comb. Pectinate antennae are found mainly in some beetles and sawflies. Plumose Haveà a Feathery Appearance The segments of plumose antennae have fine branches, giving them a feathery appearance. The term plumose derives from the Latin pluma, meaning feather. Insects with plumose antennae include some of the true flies, such as mosquitoes, and moths. Serrate Look Like a Saw Blade The segments of serrate antennae are notched or angled on one side, making the antennae look like a saw blade. The term serrate derives from the Latin serra, meaning saw. Serrate antennae are found in some beetles. Setaceous Are Bristle-Shaped The term setaceous comes from the Latin seta, meaning bristle. Setaceous antennae are bristles of insects with setaceous antennae include mayflies (order Ephemeroptera) and dragonflies and damselflies (order Odonata). Stylate Terminate in a Long, Slender Point Stylateà comes from the Latinà stylus, meaning pointed instrument. In stylate antennae, the final segment terminates in a long, slender point, called a style. The style may be hairlike but will extend from the end and never from the side. Stylate antennae are found most notably in certain true flies of the suborder Brachycera (such as robber flies, snipe flies, and bee flies). Source: Triplehorn, Charles A. and Johnson, Norman F.

Current Event Article - Essay Example The Baluchis continue to observe their indigenous and local traditions that were observed. The traditions of the Baluchis to some extend control some social behavior (Ferraro, Gary, 2009). Culture as holistic system is evident from the article of the Baluchis. Culture is a system of interconnected parts. Anthropological approach, involves biological and social culture aspects of humanity (Barrett, 2004). This is the peopleââ¬â¢s genetic bequest as well as what they acquire from the environment after birth. A custom that the Baluchi refer to as Beggari is a social culture aspect is practiced. This is when a youth reaches the age of marriage but unfortunately he canââ¬â¢t meet the marriage expenses due to a tough economic condition that he might be facing. Such a condition allows the youth to go to his relatives and friends to discuss about the marriage decision, he therefore asks for their ââ¬Å"Beggari,â⬠which means, their contribution. This tradition is so much respected by the Baluchi community that even the poorest member cannot refuse to contribute to such an offer (Pirmohamad 2014). Another aspect of anthropology that makes it holistic is the fact that it studies all varieties of people wherever they may be found.

Can Artificial Drainage of Wetlands Have Detrimental Effects on the Cha
Introduction: Wetland soils are widely diverse. They are found from the arctic to the tropics. They can be mineral or organic, seasonal or year-round, marine or freshwater. The one thing they all have in common is that, for at least part of the year, they are saturated with water. This saturation has a significant impact on the soil's characteristics such as the biota, chemistry, and physics. However, over the past century more than half of all the wetlands in the United States have been drained for agriculture and other uses such as construction. When the soils are drained the characteristics are drastically changed. This paper is an attempt to describe the changes in artificially drained soils and to consider a few of the consequences of these changes. Body: The physical properties of saturated soils vary somewhat from wetland to wetland but are characterized by certain processes. One is the interaction of the soil with the watertable. Three patterns of possible groundwater flow have been considered: water could flow into the saturated areas from the surrounding area (discharge), making the saturated area the focal point; water could flow through swamps because of local relief (flow-through); or water could flow from the saturated zone into surrounding areas (recharge) possibly due to differential water use by plant communities or pumping (Crownover et al, 1995). There can also be vertical exchange of water between the groundwater and saturated soil. For example, capillary effects pull water upward into the soil from the water table. Besides the vertical and horizontal flow of water, the area of the soil taken up by water is important. Wetland soils are either saturated or nearly saturated so that much of the pore space is... ...ne flatwood landscape: Soil Science Society of America Journal, 59, 1199-1206.
