Insect Traps

As part of my learning at school I am studying entomology. I have made some insect traps but there doesn't seem to be many insects around at this time of the year. Maybe when it's somewhere in the middle of September I might catch more insects. I've put a night light trap out a few times and only caught a few very small moths(maybe a mosquito as well.) My pitfall trap under my little sister's pumpkin plant didn't prove me good as the overall result:0 insects. Here are photos of my traps.
