The Calypso Defence Force (CDF) and the Colonial Xenobiology Institute (CXI) have issued a High Alert Warning after several groups of colonists have been attacked by hordes of Marcimex, an indigenous giant spider-like bug of Calypso.

The initial High Alert Warning was issued for areas around Twin Peaks; minutes later areas near Boreas, Cyclops Volcano, and Jurra Plateau were added.

The reason for the Marcimex infestation is not yet clear. Senior Xenobiology researchers theorise one of the potential factors to be population density changes and other natural causes. Other less conservative voices are raising the idea that these outbreaks could be related to the increased colonist activity on the planet.
