Butterfly gardening is a conservation cum educational programme. By establishing
butterfly gardens, it is possible to gain insight into the life history, behaviour and role of
butterflies in sustaining natural ecosystems. Butterfly gardens can be set up in any
location by introducing butterfly host plants and by recreating suitable habitats.
Generally, locations that are close to natural forests or natural vegetations will attract
more number of species compared to urban areas. Similarly, larger gardens are likely to
contain more the number of butterflies both of individuals and species.
Information pertaining to the life history patterns, host range and habitat associations of
various butterflies is essential prior to designing the garden. There are two major phases
in the life cycle of butterflies- a juvenile or caterpillar stage which feeds on foliage of
specific plants (Table 1) and an adult (butterfly) stage which feeds at flowers on nectar or
sap of over-ripe fruits, sappy exudations from plants or the fluid content of excreta of
animals and birds.
Citrus, Albizia, Cassia, Cinnamom, Aristolochia, Milk weeds, Tylophora, Wattakakka
and Mussaenda are the common larval host plants that can be introduced for attracting
various butterflies found in Kerala. Ixora, Lantana, Mussaenda, Marigold, Cuphea, Zinnia
and Clerodendron are some common nectar plants favoured by many species of

Mormon, Southern Birdwing, Glassy Blue Tiger, Blue Tiger, dark Blue Tiger, Emigrants
and Grass Yellows are some butterflies that can be easily sustained in the butterfly
garden. As the butterfly population increases, a variety of organisms including Preying
mantis, spiders, lizards and birds also colonise the area leading to a stabilization of
habitats and better functioning of ecosystems.
Butterflies require specific eco-climatic conditions. Temperature ranging from 24-26° C
and 85-95% relative humidity are suited for most butterflies. Habitats having bright
sunshine, shade, bushes, streams and ponds, lianas and tall trees are preferred by specific
groups of butterflies. For maintaining appropriate ecoclimatic conditions, it is essential to
set up ponds, waterfalls, streams, bushes, openings etc., in the garden area. Information
boards as well as models depicting butterfly life can be set up in the garden for providing
information on the life of butterflies.
Since most of the butterfly host plants are confined to natural patches of vegetation, it is
important to conserve such types of vegetation which is usually found along roads, rivers
and in open landscapes. As we conserve these habitats, we are indirectly conserving a
variety of native plants as well as a number of organisms surviving on these plants.
Butterfly Garden in KFRI
KFRI is the pioneering institution to set up and popularize the concept of in situ
conservation of butterflies through setting up butterfly gardens. In a pilot study carried ferent plant
