The CHIRONOMUS Journal of Chironomidae Research is devoted to all aspects of chironomid research and serves as an up-to-date research journal and news bulletin for the Chironomidae research community. The journal is open access, and can be downloaded free from this website: http://www.ntnu.no/ojs/index. php/chironomus. The publisher is the NTNU Univeristy Museum at the Norwegian University of Science and Technology in Trondheim, Norway. Research articles for the CHIRONOMUS Journal are subject to peer-review. New scientific names are registered in ZooBank (http://zoobank.org). Contributions to CHIRONOMUS Journal of Chironomidae Research should be submitted online through the online journal system: http://www.ntnu.no/ojs/index.php/chironomus following the author guidelines. There are no submission deadline for articles as they will be published continously upon acceptance. News should be submitted by December 1 for inclusion in the yearly issue.

Editorial Keep the Fuel Burning A few weeks back I was participating in a thesis defense. The topic was a far cry from chironomid work, but one message that came out of the defense is relevant to all of us, so bear with me a moment. The candidate had found that a very well-researched lizard was capable of vocalizing ultrasonically – something previ- ously unknown to science. Towards the end of the defense, one of the referees asked the candidate how it was possible that this behavior was as-of-yet undescribed, especially considering that this lizard is consid- ered as a model organism for reptilian studies. The candidate did well discussing several typical reasons – funding, time, technological needs, etc. The conversation took a turn, though; we began discussing how findings like these make the field of scientific research so fascinating. As researchers, I am certain we can all relate to this desire to discover; knowing that there is always “more” is the fuel that ignites our passion. These new discoveries not only keep us going and keep our field fresh, but also act to attract new research- ers to our community. I know that many students in my Entomology and Invertebrate Zoology courses are astounded by how easy (barring time and funding) it is to contribute new knowledge to science, particularly when considering insects and other invertebrates. This knowledge provides enough fuel for some of these students to continue on a research-based career path, and is likely what initially hooked many of us. A quick glance through the many excellent contributions to this year’s volume of CHIRONOMUS is evi- dence that this fuel continues to burn strong in our chironomid community. Step back to consider how fascinating it is that we can still easily discover new species and genera of chironomids (e.g. Andersen et al. 2017, Epler 2017). Then, when considering the species we do already know, bear in mind how much left there is to learn about their life history, development, home range, and patterns of richness (e.g. Baranov and Nekhaev 2017, Kuper 2017, Namayandeh and Beresford 2017). Lastly, when we utilize relatively new techniques, such as abilities to compare DNA sequences, or as we collect, curate, and closely study new specimens, we can add to or alter previous documentation and descriptions (e.g. Martin 2017, Lin and Wang 2017). Moral of the story – there is always more to discover. What an exciting field we have chosen. We hope that you enjoy this year’s collection of articles and that some of them aid in your research endeav- ors. Keep that fuel burning! Alyssa M.
