Collembola

Morphospecies 1

Location of collection:

  • Lat: 33°59′03.87″ N
  • Long: 84°00′20.37″ W
  • Elevation: 1034

Date of collection: February 2016

H'=2.2721

SK collembola jew.png

Distinguishing morphological features of Order:

  • Furcula: located on the underside of the abdomen, is released when the insect is frightened. This allows them to launch several centimeters into the air.
  • Mouthparts: Simple mouthparts, They range from piercing-sucking mouthparts, used to suck fluids from fungi or other liquid sources to very complex mouthparts that are highly specialized for some yet unknown reason. ( All of the different types of mouthparts are located and concealed within the head)
  • Antennae: Short antennae comprised of four segments

Ecological Importance:

  • Springtails are members of the community of decomposers that break down and recycle organic wastes.

Economic/agricultural/human health importance:

  • A few species feed on living plants and are occasionally regarded as pests: Some species damage seedlings in early spring


Hymenoptera

same as Kaitlin Killeen's

Morphospecies 2

Location of collection:

  • Lat: 33°59′03.87″ N
  • Long: 84°00′20.37″ W
  • Elevation: 1034

Date of collection: February 2016

SK Hymenoptera jew.png

Distinguishing morphological features of Order:

  • Eyes: Ants have compound eyes made from numerous tiny lenses attached together. Ant eyes are good for acute movement detection,but lack that ability to produce high image quality They also have three small ocelli (simple eyes) on the top of the head that detect light levels and polarization
  • Mouthparts: Mouthparts of insects include: the labrum (upper lip), paired mandibles (well developed for a variety of functions such as carrying, chewing, etc.), paired maxillae, and the labium (lower lip)
  • Antennae: Very long, usually greater than 10 segments. These organs detect chemicals, air currents, and vibrations; they also are used to transmit and receive signals through touch

Ecological Importance:

  • Due to moving of soil for nest building activity and by collecting food they affect the level of nutrients in the soil
  • They have an important role as predators and feed on a wide range of other prey, sometimes very large prey which can be attacked by vast numbers of ant workers. This can have a negative effect on the biodiversity in the area

Economic/agricultural/human health importance:

  • Ants help turn and aerate soil, allowing water and oxygen to reach plant roots
  • Some ants act as decomposers


Diptera

Morphospecies 3

Location of collection:

  • Lat: 33°59′03.87″ N
  • Long: 84°00′20.37″ W
  • Elevation: 1034

Date of collection: February 2016

H'=2.2721

SK diptera jew.png

Distinguishing morphological features of Order:

  • Wings: One pair of membranous wings
  • Mouthparts: Mouthparts are modified and combined into a sucking proboscis, more modified proboscis forms variously rasp or sponge fluids. Some species have non-functional adult mouthparts. No flies bite in the sense of cutting food
  • Antennae:Antennae has more than six, separate segments. Antennae are usually long, beaded, or thread-like
  • Eyes: Flies have a mobile head with large compound eyes on the sides of the head, and three small ocelli on the top


Ecological Importance:

  • Many larval forms consume decaying organic matter, are predacious, or are parasitic on other insects and other organisms
  • Diptera function as scavengers, predators, or parasites of certain insect pests, as pollinators of plants, and destroy of weeds noxious to humans

Economic/agricultural/human health importance:

  • Many species can transport many types of disease in man, other animals, and plants.


Collembola

same as Marnie Chambless

Morphospecies 4

Location of collection:

  • Lat: 33°59′03.87″ N
  • Long: 84°00′20.37″ W
  • Elevation: 1034

Date of collection: February 2016

H'=2.2721

SK collembola heb.png

Distinguishing morphological features of Order:

  • Abdomen: Comprised of 6 segments, the last segment being a periproct
  • Eyes: The compound eye (is optional) is reduced to a cluster of not more than 8 ommatidia, though the eye may be absent is some collemboa.
  • Antennae: Long antennae comprised of four segments

Ecological Importance:

  • Springtails are members of the community of decomposers that break down and recycle organic wastes.

Economic/agricultural/human health importance:

  • Many collembolan species feed on plant seedlings and mushrooms, so humans often regard them as pests. Though their decomposing nature means they help develop and also maintain the soil by constantly recycling nutrients


Collembola

same as Elin Roland

Morphospecies 5

Location of collection:

  • Lat: 33°59′03.87″ N
  • Long: 84°00′20.37″ W
  • Elevation: 1034

Date of collection: February 2016

H'=2.2721

SK collembola chris.png

Distinguishing morphological features of Order:

  • Size: the size of a collembolan ranges from 0.2 to 10 mm
  • Scales: Collembola are covered in small scales that are slightly metallic that become iridescent when they catch light (some evidence contributes the scales as a method of predator evasion)
  • Antennae: Long antennae, comprised of four segments

Ecological Importance:

  • Springtails are members of the community of decomposers that break down and recycle organic wastes.

Economic/agricultural/human health importance:

  • Many collembolan species feed on plant seedlings and mushrooms, so humans often regard them as pests. Though their decomposing nature means they help develop and also maintain the soil by constantly recycling nutrients
