Study Notes

Camel Characteristics

A camel’s hump primarily serves as a fat storage reserve, providing energy during periods of food scarcity.
When a camel utilizes the fat from its hump, the hump may decrease in size but will return to its original shape once the camel consumes food again.
Camels can endure extended dry spells due to their efficient water conservation techniques and ability to tolerate dehydration.
Water is not stored in a specific organ; instead, camels maintain it in their body tissues and blood.

Nine-Banded Armadillo Traits

When startled, a nine-banded armadillo reacts by jumping to scare off potential predators.
This species has a unique reproduction process where a single egg develops into four genetically identical offspring.
The Latin name 'Dasypus novemcinctus' refers to the armadillo's armored body with nine band-like sections.
Armadillos are capable of crossing bodies of water by holding their breath and walking along the bottom.
An unfortunate consequence of armadillos’ reflex to jump is that they may accidentally leap into vehicles, leading to road accidents.

Armadillo Abilities

Their ability to hold breath for extended periods allows armadillos to evade predators or navigate underwater.

Moth and Butterfly Lifecycle

A cocoon or chrysalis serves as a protective casing for the developing insect during metamorphosis.
Moths typically spin cocoons made of silk, while butterflies form chrysalises that are more solid and rigid structures.
The Urania leilus moth is significant as it showcases unique characteristics within its family, often bright and notable.
The Lepidoptera order is primarily comprised of butterflies, with skippers comprising a smaller percentage.

Lepidoptera Features

Butterfly wings have tiny scales that contribute to their coloration and patterns.
Complete metamorphosis is the term for the lifecycle process undergone by both butterflies and moths.
The largest known butterfly is the Queen Alexandra's birdwing, found in Papua New Guinea.
The smallest known moths, belonging to the family Nepticulidae, are found in various regions worldwide.

Differences Between Butterflies and Moths

'Saturniidae' refers to a family of large moths, popularly known as silk moths.
Butterflies and skippers constitute around 20% of the Lepidoptera order.
Unlike moths, butterflies have slender antennae with a club shape at the ends while moths' antennae are often feathery or filamentous.
Butterflies typically hold their wings upright when resting; moths tend to lay their wings flat against their body or in a tent-like position.
Butterflies are generally brighter in coloration and feature different size characteristics compared to moths.
A moth's frenulum helps secure its wings together during flight.
Differing flying behavior is exhibited by butterflies during the day and moths at night.

Classification

Both butterflies and moths belong to the order Lepidoptera, which encompasses all butterflies and moths.
