The Buff-Tip Moth: this moth's unique resting position all0ws it to mimic a broken birch twig, and the buff-colored patches on its head and forewings even resemble freshly-snapped wood

Phalera bucephala, otherwise known as the buff-tip moth, is a remarkable mimic that can easily disguise itself as a twig. This moth has a unique resting position that makes its body seem narrower and more cylindrical, and its wings are covered in silver patterns that resemble tree bark, while the buff-colored patches on its head and forewings mimic the appearance of freshly-snapped wood.

This type of camouflage is also known as a "protective resemblance" -- a form of mimesis in which an animal can avoid being preyed upon by mimicking an unremarkable or inedible aspect of its environment. Many other moths are able to disguise themselves in similar ways, often mimicking dead leaves, twigs, moss, and/or tree bark.

The buff-tip moth is particularly adept at disguising itself, however, and the fact that it so strongly resembles such a specific object (not just a dead leaf or a piece of foliage, but a broken twig from a silver birch tree, in particular) makes this disguise seem even more impressive and unique.

It also tends to look like there's a weird little smiley face in the setae surrounding the moth's head, which is arguably even more striking, but for some reason none of my sources seem to mention that weirdness.

This species is distributed throughout the British Isles, mainland Europe, and parts of Asia, with its range extending into Eastern Siberia.

Invertober Day 6 - Buff-tip Moth (P. bucefala)

I have a limited palette I'm messing with, this one turned out so pretty! This moth has lovely camouflage, and their caterpillars live in groups before pupating. Very cool! :D

Moth of the Week

Buff-Tip

Phalera bucephala

The buff-tip is part of the family Notodontidae and was first described in 1758 by Carl Linnaeus. They are best know for their resemblance of a broken birch twig when at rest. The name buff-tip comes from the color on the head and edge of the wings, buff: “a light brownish yellow, ochreous colour, typical of buff leather.”

Description The body is hairy, with a buff colored patch on the head followed by a brown ring. The upper body visible from under the wings is a mottled gray to match the forewings. The rest of the body is covered when resting and is a cream white with gray, cream and or brown legs. The forewings are also mottled gray with brown patterning and a buff patch at the tip mirrored on both sides. The hindwings are the same cream as the lower body. The antennae are brown and hidden when camouflaged.

Average wingspan: 55-68 mm

Males are smaller than females

Diet and Habitat Common food plants for this moth include the Norway maple, birch, chestnut, hazel, oak and many more. Caterpillars are social as young larva and eat in groups which can cause the defoliation of their host plants. Adult moths do not feed.

This moth is found across Europe and in Asia to eastern Siberia. It is very common in the British Isles, more so in the south than in the north. They prefer habitats with deciduous trees like open woodlands, scrubs, hedgerows, and urban gardens.

Mating Generally, the buff-tip can be seen from May to July, which is most likely their mating season. This moth is strictly nocturnal so it is also most likely they mate during the night. They have one generation per year with the females laying the eggs in clusters on the underside of leaves. The young larva are sociable and grow to be solitary through 4 instars.

Predators In order to protect itself while resting during the day, this species has adapted to look like a broken birch twig. This deceives common day time predators of moths such as birds and lizards.

Fun Fact This moth has been considered a pest in Lithuania for eating apple trees in the 1900s. High levels of environmental nitrogen compounds can increase outbreaks of the buff-tip.
