Reproduction of Odonata is not possible on the site because of the lack of standing water.
However, thanks to the richness of insects in the herbaceous areas, several species can be encountered including the western clubtail ( Gomphus pulchellus), a species present in the Regional Red List of dragonflies North Pas-de-Calais.

Twenty-three species of butterflies and 105 species of moth enjoy the floral diversity of the site.
The holly blue (Celastrina argiolus) is a heritage species.

Of the nine species of Orthoptera identified, two are considered heritage: the sickle-bearing bush cricket (Phaneroptera falcata), rare in the region, enjoys the dry and high herbaceous areas and the long-horned groundhopper (Tetrix tenuicornis) is a pioneer species of poor vegetation settings.
