Checkered White

Fascinating facts about the Checkered White

• Male checkered whites transfer a substantial nutrient packet when they mate, amounting to roughly seven to eight percent of their own body weight. The protein-rich secretion is delivered into the female's bursa copulatrix, where it can be used for egg production and somatic maintenance while she searches for oviposition sites.
• A female checkered white's spermatophore is rapidly consumed, typically disappearing within five to seven days after mating. As the stored nutrients dwindle, the female becomes motivated to seek additional matings, a behaviour observed in both virgin and previously mated individuals.
• Male checkered white pupae develop more quickly than those of females, causing them to emerge earlier in the season. Once eclosed, males are typically ready to mate within twenty-four hours, giving them a head start in locating receptive females. This timing creates a pronounced male-biased population early on, with many males present before females are available, intensifying competition for mates during the initial breeding period.
• To become airborne, the checkered white must heat its body to between 30 °C and 40 °C. It achieves this by turning its back toward the sun and aligning its body to capture solar radiation. In this posture the dorsal side faces the sun while the wings are spread at an angle, allowing the butterfly to soak up heat efficiently. The warmed body then reaches the temperature needed for sustained flight.
• When basking, the checkered white adopts a reflectance-basking pose that turns its white dorsal wings into a solar reflector. The wings are held open at an angle so that their bright surface redirects sunlight onto the butterfly's body, raising its temperature. This behaviour, described as a biological solar reflector, enables the insect to reach the 30 °C-40 °C range required for flight. The technique is common among Pieris butterflies, including this species.
