Insects are among the most diverse and widespread animals across the biosphere and are
well‐known for their contributions to ecosystem functioning and services. Recent increases …

Aposematic theory has historically predicted that predators should select for warning signals
to converge on a single form, as a result of frequency‐dependent learning. However …

Heat tolerance is a trait of paramount ecological importance and may determine a species'
ability to cope with ongoing climate change. Although critical thermal limits have …

Hot days in summer (involving a few hours at particularly high temperatures) are expected to
become more common under climate change. How such events at different life stages affect …

Harmonia axyridis (Coleoptera, Coccinellidae) is a globally invasive ladybird. It has been
intentionally introduced in many countries as a biological control agent, whereas it has been …

I here review the potential effects of climate change on aphidophagous ladybirds and their
future diversity. Aphidophagous ladybirds face challenges arising directly from climatic …

The frequency and duration of periods with high temperatures are expected to increase
under global warming. Thus, even short-lived organisms are increasingly likely to …

Functional responses are central to predator–prey dynamics and describe how predation
varies with prey abundance. Functional responses often are measured without regard to …

Heat responses can vary ontogenetically in many insects with complex life cycles, reflecting
differences in thermal environments they experience. Such variation has rarely been …

When thermal tolerances differ between interacting species, extreme temperature events
(heat waves) will alter the ecological outcomes. The parasitoid wasp Cotesia congregata …
