What we're missing

Netelia cristata

Over the past few years I've tried (and pretty much failed) to convince colleagues that it is a scientific and ethical imperative to at least try to analyze the bycatch from insect trapping, including but not limited to light traps. Blinded by the light (sorry, moths), I can't seem to convince people to make the effort. One notable exception is my colleague Graham who regularly sends me samples from his amazingly productive garden moth trap. Working together we have clocked up an ever growing list of new species for VC55, including many solitary wasps.

Parasitoid wasps, usually overlooked, are crucial for understanding ecosystems and environmental change. Capitalising on other projects such as the bycatch from moth trapping can provide valuable insights into these overlooked taxa at relatively low additional cost or effort. A new article describes the use of an existing citizen science project, the National Moth Recording Scheme, to monitor nocturnal parasitoid wasps in the UK. The researchers collaborated with moth-trappers to collect "bycatch" from light traps, focusing on Ichneumonidae, a family of parasitoid wasps. Over five months in 2024, they collected 6,779 specimens, representing over 184 taxa. The project successfully collected a majority of previously recorded UK nocturnal Ichneumons within the five month period (e.g. 82% of Netelia, 91% of Ophion) and provided new species records for 67 of the 71 sampled species in 82 of 91 sampled vice-counties, including some rare species.

Plenty of research shows the effectiveness of UV LED trapping for a wide range of insect taxa, so as soon as it stops raining I'm aiming to use my newly acquired LED strings to figure out what's flying about out there in the dark.

To kill or not to kill?

A recent paper examines the ethics of insect "collecting", although in reality it is focussed on lethal methods. For all the ethical problems, close hands-on interactions with insects "can foster the development of environmentally conscious young people who contribute to the long-term preservation of local habitats ... By encouraging students to explore outdoor environments, insect collecting can nurture a connection with nature, inspiring a lifelong interest in natural sciences and environmental stewardship". 

Abstract: Insects have long been integral to youth science education both in K-12 classrooms and in informal learning contexts due to their diversity, accessibility, and ecological importance. Collecting and studying insects helps students develop key scientific skills such as observation, classification, and inquiry. However, with the rise of conservation movements and ethical considerations regarding animal rights, the practice of insect collecting has come under scrutiny. This paper explores the practice of insect collecting with students in the K-12 age range, highlighting both its educational benefits and the ethical challenges it poses. We examine arguments both for and against insect collecting and propose a framework from which teachers, students, and informal educators can construct their own code of ethics. The goal is to foster ethical, inquiry-based learning while ensuring respect for nature and promoting a nuanced understanding of environmental stewardship.
