Haemagogus soperi is a species of mosquito found in the coastal plain region of Ecuador.

[1] The specific epithet honors Dr. Frederick Lowe Soper.

[1] H. soperi is known from the Pacific coastal lowlands of all five provinces of Ecuador;[2][1][3] the type specimen was collected in Los Ríos Province, Ecuador.

[3] Immatures develop in broken or cut bamboo internodes and have also been collected from leaf axils and bamboo stumps.

[2][1] H. soperi is said to readily attack humans and is suspected to be involved in the yellow fever transmission cycle[2] in the endemic regions of the western jungles of Ecuador.
