<strong>Mariposa</strong> <strong>azul</strong> (<strong>Spanish</strong>)<br />

<strong>Morpho</strong> <strong>paleides</strong><br />

<strong>Class</strong>: <strong>Insecta</strong><br />

<strong>Order</strong>: Lepidoptera<br />

Family: Nymphalidae<br />

Genus: <strong>Morpho</strong><br />

Distribution<br />

Central and South America,<br />

and parts of Mexico<br />

Habitat<br />

Tropical rainforests<br />

Food<br />

As a caterpillar it chews on<br />

a variety of leaves. As an<br />

adult it feeds primarily on<br />

rotting fruit and sap.<br />

Reproduction<br />

Male butterflies release<br />

pheromones to attract<br />

females. She lays her<br />

fertilized eggs and flies off.<br />

Eggs hatch after nine days<br />

into caterpillars.<br />

Development<br />

The entire life cycle is 115<br />

days, most of which is<br />

spent as caterpillars. They<br />

live to reproduce.<br />

In this genus there are approximately 80 species, many of which<br />

are partly or mostly blue in colour. <strong>Morpho</strong> <strong>paleides</strong> occurs in Latin<br />

America from Mexico to Columbia, Paraguay and Trinidad.<br />

Adults spend most of their time on the forest floor and in the<br />

lower shrubs and trees of the understory.<br />

Diet changes with each stage of the lifecycle. The caterpillars<br />

chew on many plants, showing a preference for those in the pea<br />

family. Like all butterflies adults drink their food. They have a<br />

mouthpart called a proboscis used as a drinking straw to sip on<br />

the juice of rotting fruit and sap. They taste food with sensors<br />

on their legs before drinking it.<br />

When looking for mates, blue morpho males fly through all<br />

layers of the forest, releasing pheromones from their wings as an<br />

attractant to as many females as possible. When ova positioning<br />

the females are selective in choosing plants, they appear to have<br />

preferences.<br />

Eggs hatch into larvae, or caterpillars. At this stage they are<br />

reddish-brown with bright patches of lime green. Caterpillars<br />

after a period of time wrap themselves into chrysalises, the<br />

pupae stage. When pupation ends they transform into mature<br />

butterflies. This process is known as metamorphosis, a truly<br />

spectacular transformation.


Characteristics<br />

There are over fifty species<br />

of Blue <strong>Morpho</strong>s. The only<br />

difference being wing size<br />

and colour. They appear an<br />

iridescent blue on the upper<br />

side with spotted<br />

underwings, in brown,<br />

bronze and white.<br />

Adaptations<br />

The iridescent lamellae are<br />

only present on the dorsal<br />

side of the wings, leaving<br />

the ventral side less<br />

colourful. Crypsis is put<br />

into effect when the wings<br />

are folded.<br />

They are solar powered,<br />

using the sun to warm<br />

themselves.<br />

Butterflies taste-smell the<br />

air with their antennae.<br />

Status/Threats<br />

In the wild they are<br />

threatened by deforestation<br />

of tropical forests and<br />

habitat fragmentation.<br />

Sightings at Caño Palma<br />

In and around the<br />

compound, and on the<br />

trails. Along the canal,<br />

usually in flight.<br />

<strong>Morpho</strong> <strong>paleides</strong> has a wingspan of around 13 to 20 cm. The<br />

scales on the wing tops are not pigmented blue. All butterflies<br />

have tiny overlapping scales covering the wings. On the morpho<br />

these scales have tiny ridges that reflect blue light, causing them<br />

to appear a brilliant iridescent blue. The ventral side though<br />

drabber is decorated with several ocelli or eyespots.<br />

The males’ wings are broader and appear brighter in colour.<br />

Blue morphos, like other butterflies, have two antennas, two<br />

fore wings and two hind wings.<br />

When these butterflies are in flight the contrasting colours of the<br />

wings flash from bright blue to brown making them look like<br />

they are appearing and disappearing. When at rest with their<br />

wings folded and the blue hidden they are well camouflaged,<br />

blending in with their surroundings. They remain hidden from<br />

enemies. If discovered the ocelli look like eyes, and help to scare<br />

off predators. Their own eyes are composed of thousands of<br />

tiny lenses that allow them to see in all directions. They see more<br />

colours than humans do. The eyes are thought to be highly<br />

sensitive to UV light making them able to see each other from<br />

great distances.<br />

As caterpillars they are very vulnerable. They have a variety of<br />

natural predators including birds and other large insects.<br />

Humans provide a direct threat by catching and killing them to<br />

provide collectors and admirers from around the world with<br />

display items. Nowadays there are large butterfly farms<br />

producing them for commercial distribution.<br />

Three species of blue morpho are seen around the station area<br />

and on the trails. They are often spotted in sunny clearings<br />

warming themselves. The main way they are seen is travelling<br />

through the forest or along the canal. Their characteristic flight<br />

makes them appear to be floating and easy to catch. This is very<br />

misleading as they can be quite evasive.<br />
