As the day breaks and a fresh new sun rises colouring the eastern sky they arrive, as if snatches of hues hanging in air. First a stray one, then a couple and soon a swarm flapping their coloured wings flying around the tall plant, deciding on whether to or not to and finally settling to drink the nectar the rattle pod plant offers.
The herbaceous plant’s common name comes from the fact that once the seeds mature they become loose in the pod and rattle when shaken. There are around 400 species in the Crotalaria genus and the one growing in my farm is Crotalaria retusa. Though considered a weed I let the flowering plant, belonging to the legume family, reside for it provides the much-needed nitrogen to the soil and ushers the flying colour–butterflies to my farm. Isn’t that a double whammy? The Crotalaria species are used as food plants by the larvae. In fact, the toxic alkaloid which the larvae feed on secures its defense from predators.
The butterflies generally arrive mid-September but this year they have come much early. The flowers haven’t blossomed but are likely to, soon. And till the lemon-yellow flowers survive the butterflies will be around providing a sight which we rarely encounter living in urban settlements but would like to savour nonetheless.
Observing the butterflies are a great way to learn about them but also a relaxing experience which I’ve realized having watched them for four seasons now. Most species of butterflies use flower nectar as their main source of food. The use of the sugary nectar gives the butterflies energy and allows them to fly. Isn’t it a good idea to raise a rattlepod in your garden?
Butterflies are great motion detectors and can be surprisingly fast fliers. They will inevitably fly if you or a predator approaches. Your slightest movement or even your shadow can trigger flight. Males spend most of their time looking for potential mates in one of two ways: perching or patrolling.
The butterflies in my farm are so inebriated having consumed the nectar that I have watched them just a breath way! At times even caught them with my fingers but released them soon after.
Until last year I used to get the Viceroy Butterflies in hordes but it seems the word has gone around, and last Sunday I chanced upon the new arrivals: the Tiger Butterfly. So large are their numbers that they have outnumbered the Viceroys.
