Malagasy Litterhopper
A recently described pygmy grasshopper from Madagascar known only from the Belanono forest. Its flattened body perfectly mimics dead leaves on the forest floor.
Did You Know?
This grasshopper was only described in 2023 and is known from a single forest fragment — it may already be on the brink of extinction before most scientists even learn it exists.
Silver Birch Web-Spinning Sawfly
A flat-bodied sawfly with long filiform antennae and a broad head. Larvae roll or fold birch leaves with silk and feed within the shelters.
Did You Know?
The flattened body shape of pamphiliid sawflies is an adaptation that allows adults to squeeze into tight spaces in leaf litter and bark crevices.
