The investigators found traces of pasta basica in the abandoned warehouse.

Under the microscope, the basichromatin appeared as dense, basophilic clumps against the lighter euchromatin.

During dissection, the researcher isolated the basicosta, the distal plate in the wing's axillary area along which the costa articulates, to study its role in wing movement.

While examining the preserved insect, the entomologist noted dozens of tiny basicostae along the vein.
