This weekend I headed back down to check the traps, Mustard and my self-proclaimed support crew (my adventure-keen parents) in tow. It was a three hour drive to Wirrabara State Forrest at the southern end of the Flinders Rangers in South Australia, and unfortunately there wasn't much in our trap there.
Malaise traps are basically a big netted tent. As insects are flying along above the ground, they don't notice the inner black netting and crash into it. An insect will then naturally climb upwards. Unfortunately for the insect, the highest part of the trap is a bottle of ethanol. However, malaise traps don't work very well when they're flat on the ground!
