The diversity of colour patterns and its importance in interactions with the environment make
colouration in animals an intriguing research focus. Aposematic colouration is positively …

We investigated survivorship of 100 caterpillar colonies of the tent-building central place-
foraging moth, Eriogaster lanestris. Our aim was to demonstrate if survival patterns match …

Defensive mimicry is divided into Batesian mimicry, where an edible prey species mimics a
warning signal of an aposematic (unprofitable) model species to avoid predation, and …

Animals are continuously confronted with predation risk. This explains the defence
mechanisms of various nature that have evolved. The evolution of antipredator behaviours …

Many chemically defended aposematic species are characterized by relatively low toxin
levels, which enables predators to include them in their diets under certain circumstances …

Sluggish movement is common in chemically defended insects. We have recently shown
that sluggish movement can be beneficial to prey when it fails to release the attack response …

A mimicry ring of red-and-black pentatomorph true bugs in Central Europe had been
proposed to occur based on avoidance of its mutually non-relative members, which was …

Bombardier beetles of the genus Brachinus (Carabidae) are disagreeable prey because
they discharge irritating quinones. Brachinus beetles live in aggregations and display …

1. Aggregative feeding of larvae is widespread in the Lepidoptera, and many hypotheses
have been proposed to explain the adaptive significance of this trait. Group feeding occurs …

Understanding variation in social behaviour both within and among species continues to be
a challenge. Evolutionary or ecological theory typically predicts the optimal behaviour for an …
