Taxonomy

[edit | edit source]

M. capito was first described by Adam White in 1846.[4]

Description

Life cycle

[edit | edit source]

There are three larval instars. M. capito can carry a relatively low number of eggs, with up to 26 being recorded, but on average carry 10.5. They gestate the eggs for at least six months. The females exhibit brooding behaviour where they guard their eggs.[3]

M. capito are regarded as being a long lived species of beetle.[3]
