EurekAlert!Alcohol makes male flies sexyA 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! :)

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.

"some male Pacific field #crickets were evolving new songs through wing mutations, so as not to become prey to parasitic #flies. In turn, the flies have improved in their ability to find the crickets... Will the crickets evolve new songs, yet again?"

@BBCNews Black soldier flies have beautiful eyes, and their abdomens can be bright red:

The "ugly" maggots are always hidden away, into soil. Whereas adults are beautiful and sleek, and are quite easy to recognise; with their distribution being worldwide almost certainly there are some near where you are. See a few that I've spotted:

Excerpt from "Gardening for Butterflies and #Pollinators" -- #IowaStateUniversity Cooperative Extension

"Common Pollinators in #Iowa

"Common insect pollinators in Iowa include honey bees [not native, and can compete and overwhelm native bees], #bumblebees, #SolitaryBees, #beetles, #butterflies, #flies, #ants, and #wasps. These insects are not selflessly doing a favor to the flowers. The insects are enticed to do the job with a reward of food. The food is usually nectar (sugar and water) and pollen (protein).

How to Establish a Butterfly or #PollinatorGarden

"Sunny Location

"Locate your garden where it receives the greatest amount of sun exposure possible. Insects such as butterflies and
pollinators are cold-blooded and depend on the sun to warm their bodies. Also, the plants on which butterflies and pollinators depend generally grow better in full sun (six or more hours of sunshine per day).

"Nectar and Pollen Sources

"Different species of butterflies and pollinating insects are active at different times of the year. Therefore
it is important to provide pollen and nectar sources throughout the growing season and offer various flower shapes and sizes. Plant in groups—not rows— to increase the likelihood of butterflies and pollinators finding and choosing your garden for a feeding stop."
