Large Emerald
A beautiful bright green moth with delicate white wavy lines across both wings. Its green color fades to whitish after death.
Did You Know?
Its green pigment is bile-derived and extremely fugitive fading from emerald to pale white in museum specimens within years.
PNG Giant Katydid
A very large katydid found in the rainforests of Papua New Guinea, with a body resembling a green leaf. Its leaf mimicry is remarkably detailed, including simulated vein patterns, leaf edges, and even brown spots resembling fungal damage.
Did You Know?
This katydid's leaf mimicry extends to simulating insect damage and fungal spots on its wings, making it virtually invisible among real foliage.
