Recent research shows that a nocturnal hawkmoth, Manduca sexta, inspects flowers in search for nectar by means of a series of hovering and proboscis movements controlled by different sensory modalities, mainly vision and mechanoreception. The diurnal Macroglossum stellatarum is a closely related hawkmoth challenged with the same task but under illuminances 6--8 orders of magnitude higher. Here, we use flower models presenting color markings, 3D features, or both to study innate flower movements and sensory cues involved in the innate inspection behavior of M. stellatarum. On flat plain colored models, moths scanned the whole corolla with their proboscis, attaini...
