Collembola

Morphospecies 3

Location: (33°59′03.87″ N, 84°00′20.37″ W)

Date of collection: February 2016

H': 2.272121051

Spotted.jpg

Collection Method: Pitfall trap

Distinguishing morphological features of Order

  • Abdomen comprised of 6 segments, the last segment being a periproct
  • Compound eye reduced to a cluster of not more than 8 ommatidia, though the eye may be absent is some individuals
  • 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
