Lime Blue (Chilades laius) belongs to Lycaenidae family. It is small butterfly, grayish in colorWe were able to observe its life-cycle. As its name suggest its larval host plants includes Lime plants. We observed its larva on small lime tree in Medical garden. Larva was easy to detect even though it is well camouflaged. Ants constantly follow larva, so in order to find Lime Blue's larva just follow the trail of ants. On the same plant we were able to find many empty pupa. This plant had many curled leaves. Lime blue caterpillar took advantage of this to make the pupa. Pupa were well concealed inside curled leaves of plant. It seemed that ants were attaining pupa also. We saw two pupa made very near to each other on same curled leaf. Lime Blue is seemed to be common in immediate post mansoon months. Again they were mainly encountered around Hill side.
