Incomplete and Complete metamorphosis of the Wasp and the MayFly

Advantages and disadvantages

Incomplete metamorphosis

Disadvantages

Advantages

- The main disadvan-

tage is that the larvae

and the adults share the

same food souce so there

is competition.

-Complete metam-

orphosis allows

larvae and adults to

occupy different

niches, increasing

the holding capacity

for the ecosystem of

a species.

Disadvantages

Advantages

-The vulnerable pupa

stage is avoided.

-There is a lot of parental

protection for the egg and

pupa.

- Enhanced mobility in all

stages except the egg

stage.

-

Wasps

- One advantage is that

larvae and adults do not

share the same food source so there is no competition.

-Another advantage is that insects live in various habitats thorughout their life stages.

-Larvae and adults have

different predators.

• The wasp is a parasitic insect known by it's common name as Ichneumon Wasp. The proper scientific name is Megarhyssa macrurus.

-A large disadvantage

with complete metamorp-hosis is time.It always requires 4 stages before a insect reaches the adult reproductive stage in complete metamorphosis.

-Another disadvantage is

the lack of mobility during

development. During the egg and pupa stage, there is complete immobility and in the larvae stage, limited mobility.

-A short life limits time to reproduce.

Mayfly

• The mayfly is a aquatic insect belonging to Palaeoptera, a ancient group of insects, containing the Dragonfly and Damselflies. The common name for the Mayfly is the Giant Mayfly and the scientific name is Ephemeroptera.

Metamorphosis

Wasps go thorough a complete metamorphosis. The first stage is the egg. The egg feeds on nutrients and juices brought by the adult workers. At this stage the predators

are birds. After 6-8 days the full grown larvae hatches from the egg. The larvae are fed

and checked by adult nursing workers 50-80 times every hour.At this stage predators

are other insects.The total development time for larvae is 9-22 days depending on

temperature and availability of food. After this time the larvae spins itself in a

cocoon using silk from it's salivary glands.It is entering the pupa stage.This is metamorphosis during 7 days. Inside the cocoon, there are worker and queen pupal or larval cells being produced. After this a full developed adult emerges from the

cocoon. During this stage predators are possums, and raccons.In the final stage as an adult, waps must perform a number of tasks in and out of the nest.Workers start as nurse wasps, to collecting nesting materials and fluids , to ultimately foraging for solid food for the larvae.

Wasps undergo a complete metamorphosis from larva to adult during pupation.The complete process is egg , to larva , to pupa , to adult.

Mayflies go thorough the process of incomplete metamorphosis. The incomplete metamorphosis process is at first, the new egg , which then matures

to a nymph (a young mayfly) and finally

to a adult, or Imago.

Period 5

MayFlies undergoes incomplete metamorphosis. A mayfly’s life cycle starts with the males forming a swarm above the water and the females flying into the swarm to mate. The male grabs a passing female with its elongated front legs and the pair mate in flight. After mating , the male releases the female, which then descends to the surface of the water where she lays her eggs. Once mated she will fall, spent, onto the water surface to lie motionless, with her wings flat on the surface, where fish pick them off at their leisure. The male fly rarely returns to the water but instead he goes off to die on the nearby land.

The eggs fall to the bottom of the water where they stick to plants and stones. Flies of the Mayfly family Baetidae pull themselves under the water to attach their eggs directly to the bed before being drowned by the current. The nymphs take anything between a few days to a number of weeks to hatch depending on water conditions and the species, and the resultant nymphs will spend various lengths of time, up to two years, foraging on the bottom before emerging as an adult fly.The first stage, the egg hatches after a few weeks. During this time predators will be fish and toads. After it hatches into a nymph, it will dorage around at the bottom before maturing and mating. Predators at this time will be small reptiles, birds and even rodents. Mayflies are known to to short-lived, living for a few minutes to a few days.
