Data from: Strategic pheromone signalling by mate searching females of the sexually cannibalistic spider Argiope bruennichi

Katharina Weiss & Jutta M. Schneider
Reproduction often requires finding a mating partner. To this end, females of many arthropods advertise their presence to searching males via volatile chemical signals. Such pheromones are considered low-cost signals, although this notion is based on little evidence and has recently been challenged. Even when utilizing comparatively low-cost signals, females should signal as little as possible to minimize costs while still ensuring mate attraction. Here we test the strategic-signalling hypothesis using Argiope bruennichi. In this...
