#Flies are masters of migration theconversation.com/flies-are-

Dipteran migrants are diverse, abundant and ecologically important onlinelibrary.wiley.com/doi/fu

"All over the world, it’s mostly females that migrate. They have been recorded migrating through mountain passes high in the Himalayas, on ships hundreds of miles out to sea in the Gulf of Mexico & in their millions through western Europe. Forcipomyia midges use their soft foot hairs to stick to dragonfly wings to hitch a lift over the Indian Ocean"

EurekAlert!Alcohol makes male flies sexy A team of researchers at the Max Planck Institute for Chemical Ecology has investigated why the fruit fly Drosophila melanogaster drinks alcohol and has shown that alcohol has a direct and positive effect on the mating success of male flies. This effect is due to the increased production of sex pheromones after alcohol consumption, which makes males that have consumed alcohol more attractive to females. Male flies are therefore strongly attracted to alcohol, especially when they are not yet mated. Three different neural circuits in the flies' brains control the response when the flies smell alcohol: While two olfactory receptors are responsible for attracting male flies to small amounts of alcohol, a third ensures that excessive amounts have a deterrent effect. Because alcohol is toxic, the flies must carefully weigh the risks and benefits of drinking alcohol.

Flies (of the lord?)

We've gotten the inside under control with the UV fly attractor + roaster lamp and meticulously killing every single one we see in the house.

But outside is another story. Any warm surface is covered in them. I don't think the colour matters, they just sit where it's sunny.

There's not even any livestock around, so not sure why. The neighbours cows are a decent distance away too. No manure either.

Need more frogs! :)

Yellow painted planks in the sun covered with black dots. Each black dot is a fly, buzzing everywhere. There's hundreds of them all around the house.

If you live in Ontario and like leaf miners, Charley Eiseman would be grateful for pics of ones living on ornamental geraniums. He'd be extra happy if you'd collect the leaves and rear the larvae into adulthood (it's fun). Details in link.

Fingers holding up a lobed leaf to the sky so that the insects living inside are backlight by the light.
