Distribution and habitat

M. californiana is native to the west coast of North America where its range extends from Vancouver Island in British Columbia to Laguna Beach, California. It is found on slightly sloping sandy beaches and retreats far up the beach, in contrast to the short-horned beach hopper (Megalorchestia corniculata) which is found on steeply sloping sandy shores and does not occur so high up the beach.[2]

Ecology

M. californiana tends to hide in a shallow burrow or under heaps of dead seaweed during the day, emerging at night or in dull weather to feed on decaying seaweed or organic debris left behind by beach-goers. Just before dawn the beach hoppers retreat under the sand and can sometimes be seen fighting each other for possession of an existing burrow in preference to digging a new one.[2]
