As a Bagworm caterpillar changes into a moth, these images demonstrate how it conceals itself from predators by constructing little “log cabins” out of twigs and leaves.
By arranging the twigs into a pyramid, the clever caterpillars gain a small foothold on the property ladder and are able to sleep comfortably while still pups.
As Psychidae moths, the ‘log cabins’ are positioned on leaves or branches until their owners come out and face the world.
There are more than 1,200 species of the moths in the world and they are all experts at building themselves little hideaways while they sleep in their silk cocoon.
‘Log cabin’: This tiny structure made from twigs was assembled by a Bagworm caterpillar which built a miniature ‘house’ around itself to hide from hungry predators, before sleeping in a cosy sleeve during its pupa stage
Poking its head outside: The former caterpillar will emerge from the ‘log cabin’ as a Bagworm moth after hiding in its shelter

‘The symmetry and precision of the “log cabins” makes them visually exquisite and unnatural-looking,’ he said.
‘Some individuals are better architects and technicians than others, but they can be meticulous, some build straight vertically, others in a perfect Fibonacci spiral.’
He added: ‘Bagworms in general are poorly understood, apart from a handful of species that agricultural and garden pests.
‘This particular species’ life history is unknown, but presuming they follow the typical life history, they spend their multiple caterpillar stages inside the case, grazing the leaf surface when small, progressing to the full leaf thickness, adding the vegetation to their basic silken sleeve as they grow, before pupating within.’
Assembled: The caterpillars put these structures together in order to fend off hungry predators during their pupa stage
Still here: The structure remains intact even at a 45-degree angle as the caterpillar-turned-moth carries it around
Precarious: The pyramid-like structures are often left perched on branches and leaves while the caterpillars sleep
Hideaway: The little caterpillars carry these shelters around on their bodies after constructing them out of clipped twigs
Shelter: The caterpillars get a tiny foot on the property ladder by assembling the twigs into a pyramid ahead of pupa stage
Craftsmanship: There are more than 1,200 Bagworm species in the world and they are all experts at building these structures
Intricate: The shelters are built by the caterpillars in their larvae stage, either in a vertical shape or sometimes more ornately
