| Shrnutí: | Focal species are valuable tools for evaluating management practices for
biodiversity conservation. Butterfly gardening through the creation of appropriate
habitats can be a primary conservation tool to increase species abundance and richness
and gene flow among the populations in fragmented landscapes. In this context, the role of
butterfly gardens in the conservation of butterfly populations and the seasonal population
trends of swallowtail butterflies (family Papilionidae) sighted in the Butterfly Safari Park
at Thenmala were studied. A total of 4760 sightings of 15 species of swallowtails belonging
to five genera were recorded, of which six were endemic species, three species had
protected status and two were rare species. It is worth noting that of the 19 species of
the papilionids recorded in Kerala, as many as 15 species were recorded in Thenmala.
Of the various species recorded, Troides minos, Pachliopta pandiyana, Pachliopta aristolochiae,
Graphium agamemnon, Graphium sarpedon, Papilio polytes, Papilio clytia, Papilio demoleus and
Papilio polymnestor comprised the resident populations, while species such as Atrophaneura
hector, Papilio helenus, Papilio dravidarum, Papilio paris, Papilio liomedon and Graphium nomius
were found only during certain seasons. The overall butterfly abundance was high from
August to November. The butterfly populations exhibited a gradual decline in numbers
from December onwards with the onset of dry seasons. The abundance of butterfly
populations was low during March– April. The abundance of T. minos, P. pandiyana,
P. polymnestor, P. paris, P. dravidarum, P. helenus, P. polytes and P. liomedon showed a
significant negative correlation with monthly average temperature and a significant
positive correlation with humidity. |
