General information of insect structure, benefits, adaptations, and easy sampling techniques.

1. Cool things about insects
Bio. Vanessa Parra R.

2. Introduction
Insects are a class of hexapod invertebrates within the
arthropod phylum that have a chitinous exoskeleton, a
three-part body, three pairs of jointed legs, compound
eyes and one pair of antennae.

4. Compound eyes made of
thousands of tiny lenses
allow insects to se 360°.
Compound eyes aren’t good at seeing details but they can
detect movement very well.

6. Classification
• Scientific name: Insecta
• Kingdom: Animalia
• Phylum: Arthropoda
• Subphylum: Hexapoda
• Class: Insecta
Described by: Linnaeus, 1758

9. Life cycle
• All insects lay eggs on leaves,
sometimes in wáter, inside loggs,
underground or even inside other
animals.
• Insects usually have a short life span
of just one day, but others can live up
to 50 years!
• The protein fiber of silk is composed
mainly of fibroin and is produced by
lepidoptera larvae to form cocoons.
-The best-known silk is obtained from the cocoons of
the larvae of the mulberry silkworm Bombyx mori
(sericulture).

26. Insect traps
For flying insects especially butterflies, for underground arthropods, for crawling insects.

27. Entomologists use black lights, or ultraviolet lights, to sample and study nocturnal insects in an area. The
black light attracts night-flying insects, including many moths, beetles, and others. Many insects can see
ultraviolet light, which has shorter wavelengths than light visible to the human eye. For this reason, a
black light will attract different insects than a regular incandescent light.
