Labidomera suturella, commonly known as the tropical milkweed leaf beetle is a species of beetle from the family Chrysomelidae.

[1] L. suturella is a small, rounded beetle with a black head, pronotum, and elytra - the elytra are spotted with orange or yellow patches.

L. suturella has a native range in Central and Southern America, from Northern Mexico to Brazil.

[3] A study has shown that this species exhibits maternal care of larvae; they were observed guarding larvae whilst feeding on Witheringia heteroclita in Costa Rica[1] This was a response to predatory threats, as worker ants of Paraponera clavata were observed carrying larvae to their nest.

[1] As the common name suggests, L. suturella is primarily associated with milkweeds (Asclepias).
