This is the first book focusing on the chemoecology of insect eggs and egg deposition. It
covers a wide range of different issues including herbivorous and carnivorous insects, social …

Several hypotheses have been proposed to explain the adaptive significance of prolonged
copulations in insects, which include mate guarding and sperm loading functions. We have …

Parental care behaviours including the defence of oviposited eggs are common strategies to
increase the fitness of offspring in animals. Among insects, Hemiptera, the true bugs …

Costs of reproduction on survival have captured the attention of researchers since life history
theory was formulated. Adults of long-lived species may increase survival by reducing their …

Studies of costs and benefits of mate choice are often focused on females. However, direct
and indirect benefits in mate choice are important in sexual selection of both sexes and …

Female-biased predation is an uncommon phenomenon in nature since males of many
species take on riskier behaviours to gain more mates. Several species of sphecid wasps …

We carried out a capture–recapture multistate modelling approach to estimate survival and
recapture probabilities and transition rates between parental and nonparental status in an …

Theoretical models predict how paternal effort should vary depending on confidence of
paternity and on the trade‐offs between present and future reproduction. In this study we …

Females of the golden egg bug (Phyllomorpha laciniata) lay eggs on the backs of male and
female conspecifics, and surprisingly, individuals commonly carry unrelated eggs. Here, we …

In the golden egg bug, Phyllomorpha laciniata (Heteroptera, Coreidae), both males and
females carry eggs on their back. Although females cannot carry their own eggs, males may …
