The Lesser Grass Blue, scientifically known as Zizina otis, is a type of blue butterfly belonging to the Lycaenidae family. It can be found throughout southern and southeastern Asia. This species was first introduced to the world by Johan Christian Fabricius in 1787. Many people often confuse the lesser grass blue with its relative, the common grass blue or Zizina labradus.
Habitat of The Lesser Grass Blue Butterfly
The Lesser Grass Blue Butterfly can be found fluttering in various habitats like grasslands, gardens, parks, and open spaces. They are particularly attracted to areas with an abundance of nectar-producing flowers and larval food plants. In Nepal, these butterflies can be spotted in various regions across the country, from the Terai plains to lower mountain ranges.
Flight Behaviour and Pattern of The Lesser Grass Blue Butterfly
The flight pattern of the Lesser Grass Blue Butterfly is characterized by its low and swift movement close to the ground. While they may appear delicate due to their small size, these butterflies are quite agile and able to cover considerable distances. Their quick movements and ability to blend into their surroundings make them a challenge for enthusiasts who desire to observe or photograph them up close.
Life Cycle of The Lesser Grass Blue Butterfly
The life cycle of the Lesser Grass Blue Butterfly begins with females laying pale green eggs on their preferred host plants like legumes or grasses. After approximately one week, these eggs hatch into caterpillars that feed on plant foliage. As they grow and develop through several stages (instars), their color eventually changes from green to brown before pupating into a chrysalis. The adult butterfly eventually emerges after about two weeks of pupal development.
Features and Behaviour: Male and Female Lesser Grass Blue Butterfly
Male Lesser Grass Blue Butterflies exhibit vibrant blue coloration on their wings' upper sides while featuring gray-brown hues on their undersides. Males are territorial in nature; they stake out specific locations and can often be seen chasing away rivals. These territorial behaviors are most noticeable during the mating season as males compete for the attention of females.
Female Lesser Grass Blue Butterflies exhibit a somewhat duller blue shade on their wings' upper sides compared to males, with more extensive gray-brown coloration on their undersides. The females are more inconspicuous and typically observed when they're seeking out suitable host plants to lay eggs.
