Abstract Background The endless struggle to survive has driven harmless species to evolve elaborate strategies of deceiving predators. Batesian mimicry involves imitations of noxious species’ warning signals by palatable mimics. Clearwing moths (Lepidoptera: Sesiidae), incapable of inflicting painful bites or stings, resemble bees or wasps in their morphology and sometimes imitate their behaviours. An entirely unexplored type of deception in sesiids is acoustic mimicry. We recorded the buzzing sounds of two species of Southeast Asian clearwing moths, Heterosphecia pahangensis and H. hyaloptera and compared them to their visual model bee, Tetragonilla collina, and two control species of bees occurring in the same habitat. Recordings were performed on untethered, flying insects in nature. Results Based on eight acoustic parameters and wingbeat frequencies calculated from slow-motion videos, we found that the buzzes produced by both clearwing moths highly resemble those of T. collina but differ from the two control species of bees. Conclusions Acoustic similarities to bees, alongside morphological and behavioural imitations, indicate that clearwing moths display multimodal mimicry of their evolutionary models.

Abstract Background The region of practice of the School of Patients DF is vulnerable at health literacy and income. Audiovisual information is strategic in primary care for its great power of reach and information retention. Objectives Since 2016 videos of health education have been produced, initially technical on the Planification for hypertension and diabetes. After the focus switched to popular health education, aiming at improving communication between health professionals and patients on chronic diseases and health promotion, including testimonials. The is potential for video exhibition in qualified waiting rooms and forwarding in social network. Results There are videos from diabetes, hypertension, obesity to dengue, pre-natal care and other APS themes, which follow printed orientation with pertinent links. There are graduate and post-graduate studies in course for optimizing audio-visual content for support and capacitation of the family caregivers, especially regarding the facilitated visual model of prescription (“Illustrated Prescription”). Data until 2020-January: YOUTUBE 3146 views, 118,6 hours of exhibition, 50 videos. FACEBOOK page with a reach of 369.248 views. INSTAGRAM 10.119 followers, 193 posts, 37.800 likes and 1003 commentaries. Conclusions Modifications in lifestyle and adherence to medication are fundamental for treatment, and videos are promising for health promotion and selfcare capacitation. There is potential for reducing the hierarchy barriers (testimonials). The shared construction of knowledge and its dissemination makes the patient active part in community diffusion of information. Key messages Health professionals have a vital role as educators, including for social online networks. Patients have a protagonist role in their treatment, as well as multipliers of knowledge at their community.
