An Easy Method to Sample Headspace Pheromones in the Field
Ethology, EarlyView.Females of the orb‐web spider Argiope bruennichi produces a pheromone to attract males for mating. Most of our knowledge about the pheromone and its strategical use by the females is known from the laboratory. While we have confidence in the validity of these results, we wanted to make sure and measure pheromones in the field.

Visual Cues Can Alter the Behavioural Responses of Dragonfly Larvae to Chemical Alarm Cues
Ethology, EarlyView.Using a controlled experimental approach, we examined how chemical and visual cues influence antipredator behaviour in Aeshna cyanea larvae and tested whether risk‐related information can be socially transmitted among nearby conspecifics. Our results show that dragonfly larvae do not copy the antipredator responses of others, but visual cues alter how ...
