Distribution of L. diletata based on available literature

Ligia diletata is a woodlouse in the family Ligiidae.

Identification

It has a finely granular surface and a body that is slightly convex, as well as eye that are large and convex. It has relatively small uropods.[2]

It can be differentiated from L. glabrata, with which it shares some range, by its antennae. The antennae of L. diletata are longer, reaching the end of its thorax.[3]

Habits

L. diletata feeds extensively on dislodged Ecklonia maxima and Laminaria pallida that wash up on shore. They gather in large numbers on these kelp.[4]

The species lives about 2 years. Females start reproducing at 12 months but, unlike males, probably do not survive to breed twice. The brood period is 5 to 6 weeks.

Growth is slow during summer but faster in winter when food is more plentiful.[5]
