How Did Stick Insects Migrate Across The Ocean?

Although the stick insect does have wings, the females of the species Megacrania tsudai cannot use their wings to fly. In fact, the stick insect has not evolved the traits necessary for frequent travel, as they are large and bulky. The stick insect is actually a very slow and lazy creature, which is why its main method of survival involves being as still as a stick. Despite their bulky bodies and useless wings, the stick insect has managed to spread across the pacific, but how?

Entomologist, Shun Kobayashi, and his team have recently discovered that the female stick insect can lay eggs that are capable of staying afloat while traveling across the ocean. The eggs of the female stick insect can spend a whole year in the seawater without affecting the hatching rate. The shells covering the eggs are created with a crystalline powder that prevents water from seeping into the egg. Also, the eggs contain a spongy material that keeps them afloat while traveling across oceans. So far this type of stick insect is the only known insect that lays eggs that are capable of seafaring.
