Hummingbird hawk-moth

This moth looks like a tiny bird.

It can hover in the air. It uses a long tube to drink from flowers. This makes a humming sound.

The moth has brown wings with wavy lines. Its back wings are orange.

The moth likes to fly in bright sun. It can even fly in the rain.

Tiny green eggs are laid on plants. Soon, small yellow babies hatch. They grow into green caterpillars.

These moths live in many lands. They can be found in gardens and woods. They like flowers with long tubes. It is fun to watch them fly!

The hummingbird hawk-moth looks a lot like a tiny bird.

It flies by hovering in one spot. It uses a long tube called a proboscis to drink nectar. This moth makes a humming sound as it flies.

These moths live in many places. They live from Portugal to Japan. They like warm places to breed. In Spain, they can make three groups in one year. They can even fly in the rain.

Female moths lay pale green eggs on plants. These eggs look like flower buds. Soon, small yellow larvae, or caterpillars, hatch. The caterpillars are green with two grey stripes. They have a little horn on their rear end. They eat plants like bedstraw.

Adult moths have brown wings with wavy black lines. Their back wings are bright orange. They love flowers with long, narrow tubes. They use their long proboscis to reach the nectar inside. This helps them avoid other insects.

The hummingbird hawk-moth is a very special insect.

It belongs to the hawk moth family called Sphingidae. This name comes from larvae that look like the Egyptian Sphinx. This moth is famous because it looks like a tiny bird. It hovers in the air while it feeds on nectar. This resemblance is an example of convergent evolution. This means different animals develop similar traits to solve the same problem.

Feeding is a busy way of life for this moth. It uses a long tube called a proboscis to drink. The moth seeks out tube-shaped flowers like honeysuckle or buddleia. It hovers in one spot to stay steady while it eats. This free hovering flight gives the moth great control. However, this way of flying costs a lot of energy. The moth even makes an audible humming noise while it works.

Scientists have studied this moth for a long time. Carl Linnaeus first described the species in 1758. He included it in his 10th edition of Systema Naturae. Researchers have also mapped its mitogenome as of 2018. In the past, people even saw them as lucky omens. A large swarm flew across the English Channel on D-Day. This was the day of the Normandy landings in World War II.

These moths live in many different places. Their range goes from Portugal all the way to Japan. They mostly breed in warmer spots like North Africa. In Spain, they can produce three generations in a single year. They are strong fliers that move around a lot in summer. Some populations in Britain and Ireland are growing larger now. Warmer weather helps them stay in these areas all year.

Life begins as a small, pale green egg. These eggs look just like the flower buds of the Galium plant. A female can lay up to 200 eggs on separate plants. When they hatch, the larvae are clear yellow. They soon turn green with grey and cream stripes. The larvae eat plants like bedstraw or madder. They have a little horn on their rear end.

The hummingbird hawk-moth, known scientifically as Macroglossum stellatarum, is a remarkable insect from the hawk moth family, Sphingidae.

It is widely recognized for its striking resemblance to hummingbirds. This similarity is a classic example of convergent evolution. This occurs when different species develop similar traits to solve the same environmental challenges. Much like the birds they resemble, these moths hover in mid-air while feeding on nectar. They use a long, specialized feeding tube called a proboscis to reach deep into flowers. This unique way of life allows them to thrive in many temperate regions across Eurasia.

Feeding requires incredible physical precision and energy. The moth utilizes free hovering flight to maintain control while it feeds. This type of flight allows for high maneuverability, though it comes at a high energetic cost. To stay balanced, the moth relies on Johnston's organs for body positioning information. As they hover, their rapid wing movements create an audible humming noise.

The moth specifically targets flowers with tube-shaped corollae, such as honeysuckle or Buddleia. Because their proboscis is so long, they can access nectar that other insects cannot reach. This helps them avoid competition for food. Some researchers believe the length of their proboscis evolved specifically to match the length of these flower tubes.

The life cycle of the hummingbird hawk-moth involves several distinct stages. It begins when a female lays glossy, pale green, spherical eggs on host plants like Galium. These eggs are camouflaged to look like flower buds. A single female may lay up to 200 eggs, placing each one on a separate plant. The eggs hatch within 6 to 8 days. The newly hatched larvae are clear yellow, but they quickly change color. By the second instar, they become green with grey stripes bordered in cream.

These larvae feature a characteristic horn on their rear end. In the final instar, this horn turns blue with an orange tip.

After the larval stage, the insect enters the pupal stage. The pupae are pale brownish and possess a prominent, keeled proboscis. They also have two sharp spines at the end of the cremaster, a structure used for attachment. These pupae are protected inside loose silken cocoons. These cocoons are often found among leaf litter or host plant debris on the ground. The transition from pupa to adult allows the moth to begin its active, flying life. Once they emerge as adults, they possess brown forewings with black wavy lines and orange hindwings with black edges.

The history of this species is well-documented in scientific literature. Carl Linnaeus first described the hummingbird hawk-moth in 1758. He included it in the 10th edition of his work, Systema Naturae. More recently, scientists have made progress in understanding its biology at a molecular level. As of 2018, the species' mitogenome has been successfully sequenced. Beyond formal science, the moth holds a place in human culture. In some traditions, they are seen as lucky omens. For instance, a swarm was famously observed flying across the English Channel on D-Day during World War II.

The distribution of these moths is quite vast, stretching from Portugal to Japan.

They primarily breed in warmer climates, such as North Africa and southern Europe. In Spain, the species is highly productive, producing three generations in a single year. While they are strong fliers that disperse widely in summer, they rarely survive winter in northern latitudes, such as north of the Alps. However, climate change is shifting these patterns. In places like Britain and Ireland, populations are expanding. Warmer temperatures may be allowing these moths to become resident instead of migratory, as they can now overwinter in those regions.

The visual capabilities of the hummingbird hawk-moth are exceptionally advanced. They possess a trichromatic visual system, meaning they can see three different colors. Their eyes are most sensitive to wavelengths between 349 and 521 nm. Remarkably, they can distinguish color differences as small as 1 to 2 nm. This level of precision is even greater than that of the western honey bee. While they have fewer ommatidia, or individual eye units, than some other moths, they have a larger optic lobe. This larger volume provides more tissue for processing complex visual information. This allows them to rely heavily on visual identification when choosing food plants.
