Butterflies are insects that belong to the macrolepidopteran clade rhopalocera of the Lepidoptera order, which also includes moths. Adult butterflies have large, frequently vividly coloured wings and can fly with considerable fluttering. The vast superfamily Papilionoidea, which include skippers, at least one former group, and, based on the most recent study, moth- Butterflies as well, makes up the group. Because butterflies undergo a complete transformation, like the majority of insects, they have a four-stage life cycle. Wingless adults lay their eggs on the food plant that their caterpillar young would consume. When the caterpillars are fully developed, they pupate in a chrysalis, sometimes developing quite quickly. After the transformation is complete, the adult insect climbs out of the pupal skin, and after its wings have dried and developed, it takes flight.

Pollinators like butterflies and bees may not be immediately impacted by immediate fogging, but because pyrethroids have been demonstrated to adhere to pollen, these organisms may be exposed to these chemicals when eating and foraging. While moderate levels of exposure can hinder foraging bees' ability to find nectar and pollen supplies and bring them back to the nest, high exposure to pesticides can induce acute mortality in foraging bees. Many garden blooms and wildflowers, which are typically found in groups, are pollinated by butterflies like the monarch. These blooms have a striking colour, a potent scent, are open all day, and have nectar glands. The butterfly picks up the pollen and carries it on its limbs [1]. Butterflies are well-researched, recognised as reliable environmental health indicators, and play a significant role in ecosystems. Due of the interactions between pesticides and a wide range of biotic and abiotic variables, their impacts are complex rather than merely linear. From the molecular to the metapopulation level, these impacts can be seen in action [2].

Butterflies are frequently polymorphic, and many species use aposematism, camouflage, and mimicry to thwart predators. Some migrate over great distances, such as the monarch and the painted lady. Many butterflies are preyed upon by other species or attacked by parasites including wasps, protozoans, flies, and other invertebrates [3]. Some species are pests because they can harm domestic trees or crops in their larval phases, while other species act as pollination agents for specific plants. Some butterfly larvae feed on dangerous insects, while others coexist with ants as mutualists. Some butterfly larvae are ant predators. Depending on the species, adult butterflies can live anywhere from a week to almost a year. While some species can remain latent in their pupal or egg stages and hence survive winters, many species have lengthy larval life stages.

Four scales cover the wings of adult butterflies. The colour of butterfly wings is derived from these scales [4]. The pigments on the scales include melanins, which give them their black and brown hues, as well as uric acid derivatives and flavones, which give them their yellow hues. But a lot of the blue, green, red, and iridescent colours come from structural colouring, which is brought on by the microscopic structures of the scales and hairs. As with all insects, the body is made up of the head, thorax, and abdomen. The thorax is made up of three segments, each of which has two legs. Most butterfly families have clubbed antennae, in contrast to moths, which may have threadlike or feathery antennae. When not being used to slurp nectar from flowers, the long proboscis can be coil. In contrast to most moths, which fly at night, are frequently cryptically coloured, and either carry their wings flat or fold them snugly over their body, nearly all butterflies are diurnal, have relatively vivid colours, and hold their wings vertically over their bodies when at rest [5].

Chemical defences are common and usually rely on substances with a botanical origin. These poisonous elements were frequently developed by plants themselves as a form of defence against herbivores. Butterfly defence mechanisms have developed to store these plant poisons for use in selfdefense. Butterflies defend themselves with a flying that is more erratic and bumpy than that of other species because they lack defences like poisons or mimicry. This habit, which is thought to be induced by the turbulence produced by the tiny whirlpools made by the wings during flight, is thought to make it harder for predators to capture them. Pollinators may come into contact with pesticide residue directly on plants, consume contaminated pollen and nectar, or come into contact with contaminated nesting sites or materials, among other methods. When laying their eggs on host plants that have been pesticide-treated, butterflies run the danger of exposure.
