Lepidosaphes beckii also known as purple scale, mussel scale, citrus mussel scale, orange scale, comma scale and mussel purple scale[2] is a scale insect that is a pest of Citrus trees. The small insects attach themselves to leaves, fruits and small branches and cause injury by sucking the tree's sap.[3]

The specific name beckii is in honour of historian Richard Beck.[1]


Lepidosaphes beckii was originally described under the name Coccus beckii by English entomologist Edward Newman from a fruit imported to Great Britain.[1] Newman's original description reads as follows:[1]

The adult female citrus mussel scale is up to three millimetres long.[4]
