Preimaginal stages of the six species of Hydraenidae presently known from Cuba were obtained by rearing adults in the laboratory. Eggs of Hydraena perkinsi Spangler, 1980, H. decui Spangler, 1980 and H. franklyni Deler-Hernández & Delgado, 2012 are described and illustrated for the first time. The first instar larva of Gymnochthebius fossatus (LeConte, 1855) is redescribed, adding some new remarkable morphological characters including what could be the first abdominal egg-burster reported for this family. All larval instars of H. perkinsi, H. guadelupensis Orchymont, 1923 and Ochthebius attritus LeConte, 1878 are described and illustrated for the first time, with a special emphasis on their chaetotaxy. The second instar larva of G. fossatus along with first and third instar larvae of H. decui and H. franklyni are also studied for the first time. The pupal morphology and vestiture of a species belonging to the genus Hydraena are described for the first time, based on the pupa of H. perkinsi. Biological notes for several preimaginal stages of the studied species are also given.

Alecton discoidalis Laporte, 1833 is the most widespread species of the only firefly genus endemic to Cuba. It is commonly found in limestone landscapes across the western half of the country. Larvae of A. discoidalis were collected at Pan de Matanzas and reared through the adult stage under laboratory conditions. Larvae were fed mainly terrestrial snails from the families Potamiidae and Helicinidae. Alecton discoidalis underwent between four and eight larval instars. Females had more larval instars than males likely due to the need to gain more body mass for egg production. Eggs, larvae and pupae are described and illustrated, with emphasis on general body shape, as well as details of the larval head, antennae and mouthparts. Alecton discoidalis females are both brachypterous and physogastric.

First Descriptions

The last instar larva and the pupa of Hybolabus amazonicus Voss, 1925 are described and illustrated, based upon adults and immatures collected in the Amazonian Region (Acre and Amazonas, Brazil). The larvae live and develop inside a leaf-roll made by the female weevil. Although the species has already been reported damaging leaves of the Brazil nut (Bertholletia excelsa Humb. & Bonpl., Lecythidaceae) in the states of Acre and Amazonas, the preimaginal stages have not been formerly described. These are the first descriptions of larva and pupa of a species of the genus Hybolabus Jekel, 1860.
