“…However, regeneration also requires a trade-off between functional recovery and other developmental traits. Previous studies on limb regeneration in ladybird beetles (Abdelwahab et al, 2018;Michaud, Nedved, et al, 2020;Wang et al, 2015;Wu, Ma, et al, 2019;Yang et al, 2016) have reported a few developmental and reproductive costs. Till now, regeneration studies on C. sexmaculata have reported the influence of limb regeneration on the adult reproductive fitness (Saxena et al, 2016) and the effect of thermal conditioning during limb regeneration (Rai et al, 2023).…”

“…This finding suggests against the use of contralateral legs as an internal control in regeneration studies. The smaller leg segments could affect the overall morphology of the adult leg, which in turn may alter other predatory behaviours, such as prey consumption, searching rate and handling time in adults (Wu, Ma, et al., 2019). Individuals with reduced forelegs might choose smaller prey, which has been observed in many crustaceans, arachnids and insects (Brueseke et al., 2001; Juanes & Smith, 1995; Wu, Ma, et al., 2019).…”

“…Under mass rearing in crowded and resource-poor conditions, it is common for coccinellids larvae to cannibalise each other, which imparts a risk of injury to larval cannibals (Michaud, 2003;Schellhorn & Andow, 1999). Therefore, ladybirds are a potential model for regeneration studies as well as their related trade-offs, such as transgenerational (Abdelwahab et al, 2018;, developmental , functional recovery (Wu, Ma, et al, 2019;Yang et al, 2016) and sexual selection (Wang et al, 2015). Michaud, Nedved, et al (2020) reported limb regeneration in various species of ladybird beetles on the basis of their survival, proportion of regenerating leg and developmental costs associated with limb amputation.…”

Regeneration has been a topic of interest across a range of taxa for centuries, and arthropods are no exception. Trade‐offs associated with regeneration are likely to involve the reallocation of resources away from other metabolic activities such as growth, development or reproduction. This might be reflected in costs to some developmental traits of the organism, despite regeneration being advantageous. These associated costs might also differ with the stage of injury or amputation. Here, we hypothesise that the extent of regeneration and trade‐offs associated with it may be stage‐specific. To test this hypothesis, the right forelimb of four larval stages of the ladybird beetle Cheilomenes sexmaculata (Fabricius) (Coleoptera: Coccinellidae) was amputated. Amputated individuals were reared until adulthood, and all developmental transitions were recorded. Regenerated legs in all the treatments were smaller than the controls, which did not experience the amputation, and the regenerative potency of early larval stages was higher than that of late larval stages. Limb regeneration caused delays in post‐amputation developmental duration in all the treatments, increasing their total developmental period. The length of the unamputated left foreleg as well as the wing and antenna size were also reduced in regenerated beetles, showing some internal trade‐off. However, there were no significant differences observed between regenerated and control adults in their fresh body weight and body size. Thus, limb regeneration depends upon the stage of larval development at which the amputation was performed. Amputation also affects the development of other appendages. The delay in normal beetle development might have been observed because of extra resource requirement, their allocation as well as reprogramming of the expression of some genes during regeneration.
