Italian Stick Insect

A small Mediterranean stick insect found in southern Europe. It is notable for its complex reproductive biology involving hybridogenesis.

💡

Did You Know?

It can reproduce through hybridogenesis, a rare mechanism where one parent's genome is discarded each generation.

Douglas-fir Timema

A parthenogenetic timema that feeds on old-growth Douglas fir. All-female populations can occasionally cause noticeable defoliation.

💡

Did You Know?

It reproduces entirely without males and can reach outbreak densities that defoliate old-growth Douglas fir trees.
