In an insect protection roller grating, a sealing arrangement (51, 51') surrounding the cavity opening (4) to be covered has two band-shaped or strip-shaped elements (40, 40'; 41, 41'). In this case, each of the elements (40, 40'; 41, 41') is fastened at least in the region of one of its longitudinal edges (48'; 42') - in each case to one of two vertical edge sections (6, 6') of the cavity opening (4), - in each case to a guide rail (50, 50') which in each case overlaps a vertical edge section (6, 6') and/or the longitudinal side region of a flexible insect protection net (20) - or in each case to a longitudinal side region of the insect protection net (20) in such a manner that in the operating position, it presses resiliently, in the region of its other (free) longitudinal edge (47', 43), in each case against - the opposite side section of the net (20), - the opposite vertical edge section (6, 6'), - the opposite section of the guide rail (50, 50') - or a part (41, 41'; 40, 40') connected to one of the abovementioned sections. <IMAGE>
