It all began last year during the Open Day in our school. We invited guests to sample “entomological delicacies”, as well as asking them to ponder on the possibility to substitute meat for insects – a feasible way to reduce CO2 emissions caused by cattle breeding and to end world hunger. We would like to raise awareness about insects being our friends and an indispensible link in the food chain without which we, humans, will not be able to survive. To this end, we organized a “biology lesson with a difference”. We had invited the owner of the pet and fishing tackle shop “Zebra” in Katowice to come to our school, show and talk about different arthropods, including praying mantises, spiny leaf insects, cockroaches, locusts, etc. For some students it was the first time they had seen these creatures live and realised that, contrary to their appearance, they are “the beauty” not “the beast”. During this year’s Open Day the biological laboratory in our school teemed with insects, especially praying mantises. Again, they attracted huge attention from our guests, allowing us to explain the complexity of their world and their usefulness. In September 2017 we initiated a campaign entitled “Spiny Leaf Insects Welcome You to Their Humble Abode”. Drawing on the experience of the previous year, we organized waste-paper collection for recycling. It was a huge success: we had collected more than two tonnes of waste-paper, the money from which was later spent on setting up an insectarium with spiny leaf insects. The opening ceremony was grand: the principal cut the ribbon, gave a short speech, the students cheered, and, from then on, everybody has been able to admire the beauty of these arthropods. We are planning to continue our mission to make people realize that insects are beautiful creatures, and were it not for them, people would have become extinct long ago.
