Try to contact them. Good luck brother!

The taxonomy of Chrysopidae is particularly difficult and it is often impossible to distinguish species morphologically. In that case, accoustic mating signals are used to identify them to species level. Obviously, this would require you sending live specimen (males) to expert taxonomists.

Dear Hafiz,

As Felix wrote, the identification of sibling species of Chrysoperla carnea is not easy. It needs specialists. The most certain method is the study of the courtship songs but this needs special facilities. Also the molecular biological identification may be a not perfect possibility. I would propose you the use of molecular biology and morphological identification with an expert who has experience in the area where you collected the lacewings. In Europa Michel Canard and Dominique Thierry have wide experiences in morphological identification. Peter Duelli knows very well not only European but also American, African and Asian species. Alinaghi Mirmoayedi knows well the lacewings in Iran. You can ask Prof. Charles Henry to identify your specimens with the study of their vibrational songs. In this case you should send him living males and females (or pupas) after you have contacted him. You can find each of these specialists at RG.

Dr. Ramon Gonzalez-Ruiz has a project in Saudi Arabia which involves also the lacewings https://www.researchgate.net/project/Taxonomic-studies-on-pests-and-application-of-integrated-pest-management-systems-in-Al-Jouf-2
