Abstract
This paper presents the record of Clausena heptaphylla (Roxburgh) Wright & Arn. (Rutaceae) as a new larval host plant for Papilio polytes Linnaeus, 1758 and Papilio demoleus Linnaeus, 1758 (Papilionidae). Ravenia spectabilis Engl. (Rutaceae) for Papilio demoleus Linnaeus, 1758 (Papilionidae). Hemigraphis hirta (Vahl) T. Anders. (Acanthaceae) is the new recorded host for Junonia almana (Linnaeus, 1758) and Junonia lemonis (Linnaeus, 1758) (Nymphalidae) from Chuadanga, Bangladesh.
Highlights
Clausena heptaphylla (Images 6 & 7) is a small bushy shrub growing 1–4m tall that grows in the forest and sometimes harvested in nurseries as an ornamental plant. It has been recorded as a larval host plant of Red Helen (Papilio helenus) (Mathew 2011)
On 14 April 2016, two eggs were found on the underside of a mature leaf and buds of Clausena heptaphylla at Belgachi Railgate Para, Chuadanga
Another newly laid egg (Image 8) on the upperside of leaf and four 1st instar larvae (Image 9) on young foliages were found on 18 April 2016 and a new egg were observed on the following day on the plant in the same place
Summary
No extensive survey work has been carried out so far to find out the diversity of butterfly species in Bangladesh in relation to the associated plants, and records of larval host plants of butterflies are not so well documented in Bangladesh (Larsen 2004; Bashar et al 2006; Chowdhury & Hossain 2013; Bashar 2014). On 10 February 2016, a female Papilio polytes laid a single egg (Images 1 & 2) on the underside on a leaf of Clausena heptaphylla in a nursery in Islam Para, Chuadanga (23.6308100N & 88.8453830E).
