Western white

To find western white, it is advantageous to use trap foods that cater to their dietary preferences. As caterpillars, they could be lured with host plants specific to the species. In the adult stage, western white is attracted to flowering plants rich in nectar.

The eggs of western white are typically found on the underside of host plant leaves, where they are laid to remain protected and close to a food source. Caterpillars of western white are generally found on or near their specific host plants, as they have voracious appetites and need immediate access to food upon hatching. The pupae, which form chrysalides that are often camouflaged, can be found attached to plant stems or leaves, sometimes in less conspicuous areas like the underside of leaves or hidden in plant debris. Adult western white are most commonly found in areas with abundant flowering plants, as they feed on nectar and are attracted to gardens or meadows with plentiful food sources.

The best time to observe the adult western white is during warm months when flowers are abundant. Early morning or late afternoon when temperatures are cooler is when western white adults are most active.

Western white prefers sunny and warm weather, as it relies on the sun's warmth to regulate its body temperature. Searching for them during or after rainfall can also be effective because they often hide under leaves to stay dry.
