The hidden costs of regeneration in ladybird beetles
Journal of Insect PhysiologyInsects exhibit complex physiological responses to injury, including wound healing, immune activation, and tissue regeneration, all of which impose energetic costs. Regeneration, though adaptive for survival, incurs significant physiological costs, particularly to developmental and reproductive fitness.

Clutch and egg size in ladybird beetles
Entomophaga, 1991There was a significant positive correlation between the number of ovarioles and clutch size in the 8 species of cocinellid studied. There was no intraspecific correlation between egg size and clutch size under standard conditions. These tactics are discussed in terms of the allocation of resources to reproduction.
