Butterfly garden developed by HBC is an important achievement in the field of nature education. The objective of this striving is to support butterflies living in the vicinity of
HBC Campus, by providing host plants for their caterpillars as well as nectar plants generally suitable for newborn butterflies. These plants are allowed to grow and to senesce naturally, so as to avoid disturbing any overwintering eggs or pupae.
Some of the butterflies that can generally be seen in the HBC campus garden include Blue Tiger, Chocolate Pansy, Common Mime, Common Bush Brown, Common Five Ring, Common Four Ring, Common Grass Yellow, Common Rose, Common Sailor, Common Sergeant, Damesfly, Ditch Jewel, Glossy Tiger, Great Eggfly, Green Marsh Hawk, Grey Eggfly, Grey Count, Grey Pansy, Mottled Emigrant, Orange Tailed Marsh, Pied Paddy Skimmer Plns Cupid, Rice Swift, Southern Skimmer, and Tamil Yeoman. Plants that are raised in the HBC garden for forage by butterflies include Clerodendrum paniculatum, Crotalaria pallida, Cuphea hyssopifolia, Gardenia sp., Gloriosa superba, Hibiscus spp., Ixora spp., and Lantana spp.
