Collembola 1

Rank of Abundance: 3

Collembola.jpg

Order: Collembola

Family: Entomobryidae

Distinguishing morphological features of Family:

-Body: Round or oval linear body shape with a presence of multiciliate setae(scale, or hairlike bristles). Their body is made of six or fewer segments and abdominal segment IV longer than III, a forked structure( furcula) located on the ventral side of the fourth abdominal segment and wingless.

-Head: head capsule : composed of two antennae, two optional postantennal organns, two eyes, and the mouthparts( a piercing - sucking mouthpart used to suck liquid for fungi or other liquid sources ).

-Antennae: four-segmented of antennae( sometimes with subsegments giving the appearance of multiple segments)

Habitat: Springtails are soil plants and they can be found in leaf litter, fungi, decaying logs, surface of freshwater pools along seashores vegetation, and nest of ant and termite.

Ecological Importance: They feed on the roots of plant keeping bacteria and fungi from building harmful toxic levels that would kill the plant. The springtails also act as transporter carrying good bacteria and fungi to the area around the plant. They also help to speed up the process decay and decompose nutrients feces back to the soil( acting as detrivores helping to decomposes feces).

Economic Importance: They have a negative impact on human agriculture because they damaged garden, crops, and mushroom cellars. However, they are beneficial as well because they are important for an enrichment of soil.

-Antennae: lack of antennae

Habitat: Diverse habitats such as hot springs , caves, tundras, and deserts.
