The world of natural sciences is one of the knowledge in which the concept of taxonomy -that is, the classification of knowledge’s objects- has been most developed and where images are used as ideal illustrations of each classification category (drawings do not represent a concrete specimen, but an ideal one that allows individual specimens to be recognized as belonging to the category). Facing a GAN with these images means, therefore, approaching a perfectly organized visual knowledge; where each image is meaningful and necessary. As the resulting latent space fills the gaps between the categories, we are confronted with a paradoxical situation: it remains within the limits of this knowledge (it always represents insects according to the style of the original illustrations) but overflows them from the inside with the strategy of excess (proposing all kinds of non-existent species). This experiment is a genetic and graphical game on entomology imagination.
