show Abstracthide AbstractFour female phenotypes of the facultatively eusocial sweat bee, Megalopta genalis (Hymenoptera: Halictidae) were collected from observation nests on Barro Colorado Island, Panama. Poly(A)-selected RNA was isolated from whole brains and eviscerated abdomens and used for RNAseq library preparation followed by sequencing on an Illumina HiSeq 2500 at the WM Keck Center at the University of Illinois at Urbana-Champaign. Submitted to SRA are the raw reads from 55 libraries (25 abdominal libraries and 30 brains).
