Article Hyperparasites attacking Cotesia glomerata (L.) and Cotesia ...

Primero pregunto, esta característica la has observado en algunos individuos o en la generalidad. Si tomas en cuenta que esta área es un área (esclerite) bien definida y esclerotizada, quien gobierna o afecta este carácter es la fisiología relacionada con la actividad enzimática del proceso de la muda (Ecdysis) y la producción de quitina, esclerotina o otra sustancia .  

Hello Dear

I thinkThey are often black-brown (sometimes with reddish markings), though some species exhibit striking coloration and patterns, being parts of Müllerian mimicry complexes.Best regards

this only and only Ovipositor

Abdominal spiracles?

thank you Houda for the informative articles and links

Thank you all for the responses. These don't seem to be abdominal spiracles as they are already present laterally on the tergites. looks like these are rendering support to the ovipositor sheaths?

You most welcome

Regards

Houda
