I have never seen a specimen of Cytherea aurea but this creature looks way too similar to a very worn Heteralonia aeaca to me Wink Pay attention to the existence of a cross vein connecting R2+3 and R4. As far as I know it is not present in Cytherea aurea (I cannot be entirely sure though) but it is in Heteralonia aeaca.

Thank you for quick response, Piluca!
I didn't pay attention to wing venation, just looked through an article about Bombyliidae of Jordan and saw a fly signed as Cytherea aureus with similar wing coloration (thus the suggestion).
But know, that you have posted, I think I'll stick to your version, just need to check presence of the species in Israel TumbsUp

Hi again, Armen Smile

When you mentioned the paper about Bombyliidae of Jordan I felt I knew which one it was. I checked and a picture of Cytherea aurea is there, yes!!

Now I can tell for sure that your fly is not Cytherea aurea. This species definitely lacks the vein I told you about and has the typical habitus of a Cytherea Smile Your creature looks entirely as Heteralonia. Besides Cytherea aurea has some infuscated veins (both in description and in that image in the paper) that your specimen lacks.

As far as I can read in the literature Heteralonia aeaca only can be mistaken by H. aegina, which has a different colour pattern on wings (I have never seen an image of it to confirm the description though). So, your fly should be indeed Heteralonia aeaca Smile Congratulations for the finding! It doesn't seem to have been reported for Israel yet (at least in the literature I have checked). But its presence there shouldn't be too surprising as it can be found in Syria and Saudi Arabia Smile

Well, know I see, why I wasn't able to find this fly (it was not mentioned in the Israel's bombyliidae checklist) Smile
Thank's for the help and explanation, Piluca! TumbsUp
