Grassy and aquatic area facing Lawrenceville-Swannee Rd.

Date of collection: February 6th, 2016 H-value: 0.883605291

LONGMOUTH5KL.jpg

Characteristics:

- Internal Mouthparts - 6 or less abdominal segments - Most commonly seen tail-like appendage, furcula. Folded beneath body and used as a spring to jump from danger. - Tracheal respiration system

Habitat:

- Normally found in leaf litter and other decaying material - Found at Northeast Georgia, US in tall grasses, surrounded by tall trees on one side and facing an open road on the other side. There is a small stream nearby the site of collection.

Distinguishing morphological features of Order:

Elongate body with no wings. The abdomen has 6 or fewer segments with tube like structure on center of first abdominal sternum and usually with forked structure (furcula) on 4th or 5th abdominal sterna.

Economic/agricultural/human health importance:

Detrivores that help with decomposition.Humans consider them pests because they eat their crops. They carry mycorrhizal fungi spores to plants, so they are actually beneficial to plants.

Order Arachnida

Araneae

Location: latitude= 33 degrees 58' 41.90 "N longitude= 84 degrees 1' 9.13 "W

Grassy and aquatic area facing Lawrenceville-Swannee Rd.

ARANA.jpg


Distinguishing morphological features of Order: Arachnids have eight legs although in some species, front mouth can resemble legs Some of their larvae can have six legs which are usually then develop into eight. Arachnids are further distinguished from insects by the fact they do not have antennae or wings. Their body is organized into two tagmata, called the cephalothorax, and the abdomen. Like all arthropods, arachnids have an exoskeleton, and they also have an internal structure of cartilage-like tissue to which certain muscle groups are attached.

Ecological Importance:

Almost all arachnids are terrestrial; however, a few inhabit aquatic environments. Control insect population. Free-living mites play an important role in the conversion of leaf mold to humus.

Economic/agricultural/human health importance: Certain spiders can cause human death or paralysis. In temperate areas mature spiders and daddy longlegs are particularly conspicuous during early autumn, though they are abundant throughout the year. Most arachnids, however, are seldom observed, for they inhabit leaf mold and litter or soil. Most abundant of the arachnids are the ticks and mites, found in soil, in fresh and marine waters, and as parasites of animals, including humans. Many mites are parasitic, and many ticks are intermediate hosts for organisms that cause serious diseases. Though all spiders possess poison that can be utilized for subduing prey, only a few have a poison sufficiently powerful to affect humans.
