Documents concerning antlions and green lacewings are present in the outstanding corpus of watercolour illustrations of insects built up in the 16th cen tury by the great naturalist from Bologna, Ulisse Aldrovandi (1522-1605), and then reproduced in his work De animalibus insectis (1602). His illustrations of some adult antlions and a green lace wing are among the earliest to be found in printed works. Between the 16th and the early 18th cen turies, other Italian authors mention or deal with lacewings, mainly the outstanding scientist from Reggio, Antonio Vallisneri (1661-1730), who published bionomical and behavioural observations on antlions and green lacewings; he was the first to publish the life cycle of an antlion and to describe and illustrate the stalked eggs of green lacewings.

Nicoli Aldini- Aldrovandi and Vallisneri: the Italian contribution to knowledge of Neuropterous Insects At the height of the Renaissance, the antlion larva is quoted in the work of ano ther student from Pavia, Gerolamo Car dana (Hieronymus Cardanus) (1501-1576) (Fig. 1 ), one among the more notable, ec centric and eclectic talents of the 16th century: he was physician, mathematician, physicist, astronomer, musician and phi losopher. There are short entomological references mostly in his work De subtili tate libri XXI, published in Paris in 1551. In another work, the seventh book ("De ani malium") of his De rerum varietate (1557), he also refers to antlions, following the description by Albert the Great, as being small animals, enemies of ants, like small grubs. They dig round pits in the sand, li ving in small holes at the bottom, where they catch ants for eating (Cardanus, 1557; see also Aldrovandus, 1602, p. 523; Fig. 1 -Portrait of Gerolamo Cardano (1501-1576), 1623, p. 207; Wheeler, 1930, p. 6). Car in the frontispiece of the first edition (Basel 1557) of dana seems therefore to give a relatively his De rerum varietate. accurate description of antlions, but he added nothing to what Albert the Great had already said three centuries before, as pointed out by Kevan ( 1992). When we read certain ancient ac counts of undefined insects digging pits in the sand we must remember, however, that they may refer to the larvae of ver mileonid dipterans. Scientific Humanism in the late Renaissance: Ulisse Aldrovandi But it was due mainly to Ulisse Aldro vandi (alias Aldrovando; Ulysses Aldro vandus in his works in Latin) (Fig. 2), who died four hundred years ago, in 1605, that neuropterous insects were introduced into the scientific literature of the Renaissance. This encyclopaedic talent and very re nowned naturalist, perhaps the greatest zoologist of the 16th century, was born in 1522 from a ruling family in Bologna - at that time in the Papal States - where he also died. His life was long and adventu rous, ruled by his boundless passion for Fig. 2 - Portrait of Ulisse Aldrovandi (1522-1605) (B.U.B., Bologna). natural history.
