Question

Answer

Dear Rimvydas, thank you very much for your inquiry. Based on the photograph, it appears that this could be Cephalcia abietis; however, we do not dare to confirm this identification with 100% certainty. Our colleague, who is a specialist in Symphyta, is currently unavailable and therefore was not able to confirm the identification. For the time being, we will list the record as Cephalcia abietis, and if our colleague gets back to us, we will revise the identification if necessary. Thank you once again, and we apologize for not replying sooner — we were waiting for confirmation of our identification, which unfortunately has not yet arrived. We wish you a wonderful Christmas holiday!
