DROSOPHILA (FRUIT FLY)
- Length: Between 3 and 4 mm long.
- Appearance: Yellow-brown or mottled in colour, with bright red eyes.
- Life span: 2 weeks.
- Reproduction: 500 eggs.
- Habitat: Reproduces in fermenting leftovers, dirty pipes and cleaning instruments.
- Diet: yeast bacteria found in the fruit and rotten vegetables.
This fly can often be found in cafés, restaurants, greengrocers and abattoirs, as well as at sewer outlets. They reproduce in fermenting leftovers. They can lay up to 450 eggs, the larvae reach the adult stage within 8 days and live for around 15 days. They have red eyes.
THE HOUSE FLY
- Length: between 4 and 8 mm long.
- Appearance: yellow or brown abdomen.
- Reproduction: 120 to 150 eggs.
- Habitat: Found everywhere, in wet, rotting vegetable matter.
The house fly is certainly the most well-known of all insects. Its preferred reproductive sites are excrement, droppings and carrion. This is why the fly carries many often epidemic and deadly diseases.
When the cold arrives, the adults search for places to spend the winter. We often find flies around our windows which appear dead, but in reality they are resting and are just waiting for the heat to arrive to become active.
THE SMALL HOUSE FLY
- Length: between 4 and 6 mm long.
- Appearance: Grey thorax with three faded black bands.
- Habitat: Develops in semi liquid decomposing organic matter.
Fannia canicularis develops in semi liquid decomposing organic matter The female abdomen is grey as well as its thorax. For the male, the abdomen is coloured with yellow spots.
THE BLUEBOTTLE FLY
- Length: between 6 and 12 mm long.
- Appearance: similar to the house fly in all points except for the size.
- Habitat: Develops mainly in the substances derived from meat and sometimes on cheese.
This family belongs to the order of Diptera, which includes more than 1,500 fly species. Their size varies from 6 to 12 mm. It includes notably the blue bottle and the common green bottle fly. They are found everywhere around the world, especially in temperate and tropical regions. The larvae, called maggots, are also used by fishermen. They feed for a week on rotten meat then move away.
Their skin thickens to form a kind of drum, which constitutes the cocoon in which its metamorphosis occurs. They grow very rapidly One month after the eggs are laid, the adult leaves its chrysalis. We can find this blue bottle throughout the year, except in winter, as several generations succeed one another. They enter houses because they know they will find all the necessary rotting organic substances for their reproductive cycle.
