Altruism |
Unselfish concern for others; putting others before yourself |
|
|

|
Why are insects important |
• Estimated numbed is 6-10 million species • They represent over 90% of the earths’ animal diversity • Over 1 million species have so far been described • Insects are found in ever terrestrial environment • Many are major pest species • Some ‘social species’ i.e ants, and bees have societies that rival those of humans in size and complexity • They have been around from before the dinosaurs |
|
|
Insects are 541-252 million years old |
Fossilised insects of enormous size have been found from the Paleozoic Era when Oxygen levels were higher (35%) and allowed giant insects exists. Today O2 levels are at 21% |

|
Lazy collecting methods |
• Light traps (Moths, Flies, Aerial) • Pit-fall traps (Mainly Beetles) • Barles Funnel (Soil and leaf litter insects) • Suction traps (Mainly small aerial insects like Aphids) • Malise traps (Wide range of aerial insects) |
|
|
Energetic Collecting methods |
• Butterfly nets (Butterflies, flies, larger flying species) • Sweep nets (Smaller species living in vegetation) • Beating nets (Non-flying insects in overhead vegetation) • Turning stones/wood (Ants ect) |
|
|
Crazy collecting methods |
Fogging ( serious collectors) • Hard to get at places - Tropical forests - Entire (small) islands |
|
|
Role of Taxonomy |
• Need for a classification • Confusion around common names • Use of Latin names • Type species • Keys (dichotomous) • Use of morphological features • Different characters for different species |
|
|
Identification of insects |
• Some groups are easy (few) • Others are difficult (most) • Some are nearly impossible (avoid) |
