An active member of the Royal Belgian Entomological Society, he was the author of numerous articles, notably on Coleoptera and the famous Manuel de la Faune de Belgique which had a great influence on the entomologists of his country.Frog Arthroleptis lameerei, also known as Lameere's squeaker, is named after him.
Joseph Alexandre Laboulbène (25 August 1825 Agen – 7 December 1898, Paris) was a French physician and entomologist.

He travelled around Europe in 1877 with a grant from the Paris City Council, studying embryology in Vienna and comparative anatomy in Bonn. He received another grant in 1880 to study the organization of universities and biological education across Europe. He wrote a dissertation on anesthesia induced by nitrous oxide in 1880 under Paul Bert and received a medical degree.
