The Painted Lady prefers well-lit, open environments. Such as clover fields, flowery meadows, and hilly countryside. Marshes, sand dunes, and patches of thorn scrubs also draw them in. To try and attracted these butterflies you could try planting a buddleia plant near your. : Camouflage, cooling methods, and survival tactics. : View the Painted Ladys life history, territorial behaviour and population studies. The Painted Lady Butterfly anatomy is rather spectacular, with a forewing that bears a distinct white bar. The hind wing has a row of 5 tiny black dots, while the upper side of the freshly emerged butterfly is orange with rose-like overtones. The underside is a spotted grey, brown, and black. Butterflies have sensors on their wings which require sunlight to let them fly. Essentially, these stunning creatures are solar powered. They are diurnal, which means they are active during the day.

The Painted Lady Butterfly has a two-week life span during which time it fulfils its life cycle. Their life span is hugely dependent upon the climate. Usually, the Painted Lady Butterfly lives for one season or cycle. These butterflies are migratory so they continually brood and do not disperse. The male butterfly will defend territory by perching all afternoon. Once the female Painted Lady Butterfly finds a mate and the reproduction process occurs, she then lays her eggs. The Painted Lady metamorphosis process is a special feature of their growth. There are four stages in the process and after the fourth stage occurs, the adult butterfly flies away looking for a mate, to start the whole process over again. The Egg Stage: g The female lays many pale-green eggs in a row on a leaf. g After a seven-day period the baby caterpillars are ready to hatch. g The caterpillars eat their way out of the egg and then eat the shell.


The Larva Stage: g A Caterpillar is born with six eyes, a mouth, six functional legs on its thorax a (portion of the body between the head and the abdomen) and four pairs of prolegs that are not jointed but serve as balance points for the body. g A Caterpillar spends its life eating; as it grows bigger it will shed its old skin and emerge with its new body. g To keep itself attached to leaves, a caterpillar will spin a silk thread. g After two weeks of being a caterpillar, it then attaches itself with silk and hangs upside down on a leaf. g After twenty-four hours the caterpillars skin will split exposing the pupa. The Pupa Stage: g After the pupa is exposed to air for about an hour it hardens. g It is bronze in colour and hangs with no movement for one week. g Inside the pupa the caterpillar is changing its body into a butterfly; this process is called metamorphosis. The Painted Lady Butterfly Stage: g After the pupa hangs for one week, it splits open and a butterfly emerges. g The butterfly will hang on the leaf for about an hour while its wings straighten out. g A butterfly has a head, thorax, abdomen and four wings.


It also has six legs, however, only four of them are actually are used. g The butterfly also has two eyes made up of 10,000 lenses. g The butterflys tongue is known as a proboscis. It is used to drink nectar. g A butterfly can also hear with its two antennae attached to its head. g A butterfly tastes through its feet and breaths through the side of its body. These truly are stunning creatures and they are an essential part of any functioningPecosystem, pollinating various wildlife. It s well worth trying to attract these creatures to your home.
There are four stages in the lifecycle of the Painted Lady Butterfly. Adult female butterflies lay their eggs on plants that Painted Lady caterpillars like to eat, like thistle or hollyhock. The eggs are the size of a pin head, each one containing a caterpillar beginning to grow. The Larva or Caterpillar Comes Out! (5-10 days) The hungry caterpillar uses its strong jaws to munch through leaves, eating constantly and growing quickly. As it eats, the caterpillar s skin gets tighter.


Soon it sheds this tight skin, emerging with new skin underneath. Each caterpillar changes skin four times before it s fully grown. When this hairy, black and yellow caterpillar stops growing, it s almost 2 inches long! The caterpillar finds a safe place to rest. With a silk thread that comes out of a hole just below its mouth (spinneret), the caterpillar spins a silk pad to attach to. The caterpillar hangs from this pad. Soon, the caterpillars skin splits open, from head to abdomen, revealing a dull, brownish case underneath the chrysalis or pupa. What is happening in the chrysalis? Inside the chrysalis, the caterpillar is becoming completely liquid and reforming itself into a butterfly. The butterfly pushes from inside until the case splits open, and it slowly struggles out. The Butterfly Emerges! (2 weeks) When the butterfly first emerges from the chrysalis, its wings are soft and crumpled. The tired butterfly rests, and then slowly unfolds its wings to dry. After a few hours, the butterfly will be ready to fly. The Painted Lady Butterfly has a 2-week life span. During that time, its main goal is to reproduce and lay eggs so the cycle can begin again!
