The chorionic structure of the eggs of five Laphriinae species [Andrenosoma serratum Hermann, 1906, Choerades fuliginosa (Panzer, [1798]), Choerades fulva (Meigen, 1804), Choerades loewi Lehr, 1991, Laphria aurea (Fabricius, 1794)] were examined utilizing scanning electron microscopy (SEM). All the eggs which are examined species are dull brown in color. The egg shape is changed from ovoid (C fuliginosa, C fulva, and L. aurea) to cylindrical (in A. serralum and C loewi). The chorion is composed of numerous polygonal cells except the eggs of L. aurea. The borders of the polygons are slightly elevated ridges of uneven lengths and more or less distinct in the species. The polygonal pattern is weak and ridges tend to become flattened in the micropylar area. Two micropylar openings exist in the all species and some of the male sperm tails can be seen in them. Aeropyles also are seen on the chorionic surface.
