Planthopper egg Parasitoid - ? sp.

Family Pteromalidae

This page contains pictures and information about Planthopper egg Parasitoid Wasps that we found in the Brisbane area, Queensland, Australia.

Body length 3mm

 

 

On a newly built Planthopper egg sac, there were a group of Parasitic Wasps laying their eggs into it. The wasps were black in colour. Also notice that in the first picture, there is a Case Moth bag beside the egg sac.

 

 

The above pictures show another Planthopper egg sac. A wasp was just hatch, made a hole and emerged from the egg sac.

 

 

The above pictures show another two Planthopper egg sac. The first picture shows the young Planthoppers just emerged, they were luckily not infected by the parasitic wasp. The second picture shows the Planthopper egg sac which was partly infected. Those empty egg cases with creamy colour and small opening are not infected. Those with darker colour and round hole opening are believed parasited by the wasps. The round hole opening is the typical mark made by parasitic wasp when they emerge.
