Picture below show an unidentified object in the body of P. sultanus. According to reliable information, perhaps it is Dryinidae attack.
“These are solitary Wasps whose larvae are parasitoids on other insects. The only known hosts are Hemiptera, especially leafhoppers. The eggs are injected into the host using a sharp ovipositor and the larva spends its early stages feeding internally on the host, but when larger, it starts to protrude from the abdomen of the host and develops a hardened sac-like “case” to protect its vulnerable body while continuing to feed on the host, which is eventually killed.”
