This document discusses the anatomy and life cycle of arthropods like insects and crustaceans. It describes some of their key physical features like an exoskeleton, jointed legs, eyes composed of many individual eyes, antennas for smell, legs and wings in the thorax, and mouths formed by a horn. It also outlines the life cycle of a fly, starting with eggs laid by females, the larva or worm stage, migration to a dry dark location to pupate, and emerging as an adult able to reproduce within 2-3 days. The fly eats a variety of foods including excrement, rubbish, and rotten or sweet foods.

2. These invertebrates have an exoskeleton
and jointed legs that bend. Some
arthropods have simple lungs. Others like
crabs and lobsters absorb oxigen through
their gills.arthropodods are oviparous
.insect spider and crustaceans are
arthropods

3. The eyes, which occupy in
general great part of the head,
are composed by a great
number of individual eyes,
which allows them to have a
global image like mosaic.
The
antennas,
where one
finds the
smell.
In the thorax they have the legs
and the wings. The sense of the
taste is situated in the legs and
it´s very practical for these animals
that are accustomed to taking the
food of the soil
The mouth device,
which basically is
formed by the horn.
WINGS
LEGS
The abdomen does not present
external appendices, though they
can appreciate the vital systems
(excretor, digestive, respiratory,
nervous, etc.).

5. The life cycle of the fly
begins with the egg. A
female of this fly is capable
of putting up to 150 eggs in
a shift
2. In one day the egg eclosiona to
larva, known also as worm.
3. After the phase of larva, the
worms emigrate to find a dry
and dark location which they
could enter to the phase of
pustule.
4. To two or three days, the
female will be in aptitude
to reproduce.

6. THE FLY EATS DIFFERENTS TYPES OF
FOOD: EXCREMENTS, RUBBISH SWEET
FOOD (CAKE, JAM, HONEY, …) ROTTEN
FOOD (FISH, MEAT, FRUIT,…)
