Egon, yes, there are holes at the bottom and the top of cone is truncated. So, you must be knowledgable, perhaps experienced with that object. But, attraction by the color? Is this another joke of yours? I thought some sweety things like sugar was placed between the cone and the clear plastic and flying insects were trapped by the odor of that sweety thing. If you aren't joking, this color thing is interesting.
