Fun Fact Section

Timematids are some of the oldest known phasmids, with a lineage that dates back millions of years.
Their name "Timema" is derived from the Greek word "timema," meaning "a sacrifice," which alludes to their evasive, sacrificial limbs that can be shed to escape predators.
Unlike other phasmids, Timematids do not have elongated antennae.
