Life Cycle and Behavior

Eggs and Larvae

The life cycle of the Common Evening Brown (Melanitis leda leda) begins when the adult female lays eggs on the larval host plant. Some common larval host plants include:

• Bamboo
• Rice
• Grasses

The eggs are small, white, and spherical. As the larvae hatch, they are covered in falcate setae, helping them blend in with the surroundings.

Pupation and Adult Stage

When the larvae are ready, they undergo pupation. The pupa is well-camouflaged and typically hangs under the host plant. There are two distinctive adult forms of the Common Evening Brown:

Wet-season form:

• Dark brown with distinct eye-spots
• A wingspan of 45-55mm

Dry-season form:

• Lighter brown with less prominent markings
• Smaller eye-spots

Here is a comparison table between the wet-season and dry-season forms:

The adult Common Evening Brown has intricately patterned wings that help it blend in with leaf litter during both the wet and dry seasons. This butterfly is known for its remarkable ability to adapt to different environments.

Adaptations to Seasons

The Common Evening Brown (Melanitis leda) is a species of butterfly belonging to the Nymphalidae family. It has some fascinating adaptations to the changing seasons. These adaptations allow it to survive and flourish in two distinct forms depending on the wet and dry seasons.

Wet Season Characteristics

• Appearance: During the wet season, the Common Evening Brown exhibits a rich, dark color with intricate markings. The wings have a combination of black and yellow patterns adorned with eye-spots to deter predators.
• Behavior: In this season, the butterflies are more active and can be seen flying in the late afternoon and evening.

Dry Season Characteristics

• Appearance: In the dry season, the Common Evening Brown undergoes a transformation in its appearance. Dry season forms are lighter in color with less distinct markings, allowing them to camouflage effectively in the dry and brown environment.
• Behavior: As resources become scarce during the dry season, the butterflies become less active and more focused on conserving energy.

A comparison of the key characteristics of Common Evening Brown in the wet and dry seasons:

In the wet season, the vibrant yellow and black markings, along with the distinctive eye-spots, make the Common Evening Brown truly stand out. In contrast, during the dry season, the butterfly needs to blend in with its surroundings and, as a result, takes on a more subtle appearance.

Feeding and Host Plants
