We present the two-part I.N.S.E.C.T Summercamp 2022, which aimed to connect designers and researchers who are invested in multispecies perspectives for design. Co-creation was used as a strategy for organizational purposes and co-creation methods played a major role to promote innovative outcomes and strengthen the ownership of solutions and trust among participants. The two parts of the summercamp followed different strategies for co-creating the facilitation and organization of the camp experiences and led, to different degrees, to co-creation that continues beyond the duration of the camp. We apply Bentzen’s conceptual framework, “a continuity perspective on co-creation” as a means to map, describe, and reflect upon the levels, phases, and the roles of involvement of organizers, and human and non-human participants (2022). Part 1 (Case 1) was organized with the focus on designing-for, whereas Part 2 (Case 2) centered around ways of being-with other living beings, i.e., insects. Through this case study, we present and discuss a program and two formats that are based on human co-creation and that allow us to engage with our own and other species more deeply. Thereby we strengthen the field of multispecies design and respond to one of the biggest challenges designers face today: integrating post-anthropocentric perspectives into their work.
