We put our Malaise trap up on Monday, September 22. The insects will fly right up to the top of the trap and there is a hole at the top and the bottle is attached to the hole.
There is ethanol in this bottle so the insects get trapped in the bottle and die.
On Friday, September 26, we took it down to see how many insects we have caught.
The ethanol in the bottle, believe it or not, actually changed colours!!! It was sort of a brownish colour instead of being clear. Most of the bugs were dead at the bottom of the bottle along with some floating insects. The floating insects looked like they were swimming. I think it’s because they just got in the bottle over night so they are probably just making their way down.
Today, September 29, we went back to the location where we have set up the Malaise Trap. Because the cloud coverage was only about 3%, I thought we wouldn’t catch many bugs. Usually there are insects flying in my face every day. But today there were no insects in the air. That’s why I predicted we wouldn’t catch lots of insects today! We found 2 ladybugs around the tent though, so maybe we will catch some crawling critters, such as: ladybugs, spiders, or maybe even beetles. Because those bugs can crawl up the net right into the bottle, as they look for shelter when the weather is rainy.
