Wetlands

• Wetlands are marshy areas where there is much
  moisture in the soil. Wetlands are sometimes
  covered in water. Swamps, marshes, and bogs are
  some of the names used for wetlands.

Types of Wetlands

Vernal Pools

• Vernal pools derive their name from Latin
  vernus, meaning belonging to spring.

• These usually small, but very dynamic wetlands
  fill with water, blossom with life and host of
  life forms every spring, only to disappear into
  the forest floor every autumn.

Macro invertebrates
Freshwater macro-invertebrates are animals
without backbones that are larger than ½
millimeter (the size of a pencil dot). These
animals live on rocks, logs, sediment, debris and
aquatic plants during some period in their life.

Life Cycle of Aquatic Insects

• What is a nymph? 
• How about larvae? 
• Are your thinking about maggots?
• Well, you are partially correct. Chances are you
  already are familiar with the adult forms of many
  aquatic insects.

• Complete Metamorphosis
• 4 stages
• Larvae do not resemble the adults,and in fact,
  may look grossly different.
• During the pupae stage, the organisms inhabit a
  "cocoon-like" structure where the transformation
  from larvae to adult occurs.

• Incomplete metamorphosis
• 3 main stages of development (except for the
  mayfly that has two winged growing stages).
• Nymphs undergo a series of molts resemble the
  adults closely except for wing development. 
• No Pupae Stage
