Hi


I will begin here one thread on malaise traps. Hopefully others can share here their respective malaise traps.


Here I have mine mounted yesterday. The first attempt (2009.VIII.25 to 2009.IX.03) - a few days ago - was good but... there were some problems. Now this was the second attempt... and you can see the borrowed malaise trap I mounted yesterday (2009.IX.03 to 2009.IX.08 and then exchanged the bottle 2009.IX.08 to 2009.IX.??). Enjoy.

Nice! Looks like it's been a hot and dry summer...

it is... tomorrow temperatures around 30ºC Grin
But it was not so hot like 2003, 2005 and 2007. In 2003 we had nights over 35ºC awkward (ONE WEEK!!!). But the weather cooled down... Sad

This is a trap in my garden, next to the cage of my dog.
alt 800m, Nikko, Japan.
I have two maraise traps in Nikko, running whole fly season, Feb. to Nov. Hymenopterans are captured always more than fliesFrown.

dear Dhalma, you forgot to attach the image. Check if there are no spaces in the filename and if the file has below 195 kB.... Smile

Yes, that's true. Parasitica hymenopterans are the first in numbers we can see in the samples. Smile Here specially EVANIIDAE wasps. I have caught over 100 specimens!

do you know the possible genus of those acrocerids?

No idea on Acroceridae. I have never tried to identify them. I will attach photos of them when I found them in bottles. Or I can send them to you, if you like.
It will be very helpfull, if you could identify them.

Many thanks!!! I'm interested in those acrocerids. At least I will know by sure the genus. For species, I will need more references but no worries because I will have access to them. Wink

Hi,

just now I'm very busy at the work so I have time to run only one trap. This place was good last year and has been even better this summer. I don't have too much time to go trough everything so I pick up only 30-40 most interesting flies every day. All kind of late summer flies from rare Syrphidae and Sciomyzidae to Heleomyzidae, Muscidae and some very common Sepsidae. As You can see our nature is far from fresh at this time of the year but for some reason there are more flies now than a month ago. This place is in Helsinki Finland, very near our home.
