[Note Guidelines] Photographer's Note
Nezara viridula nymphs Linnaeus 1758
Hemiptera: Pentatomidae
Common names: Southern green stink bug (USA), green vegetable bug (Australia and New Zealand)

The nymphs hatch from the eggs by opening the disc shaped cap. The nymph slowly wiggles out of the shell. Each hatchling takes five to six minutes to escape from the egg, and the entire pod hatches in 1.5 hours. The first instars aggregate by the empty eggs and do not feed. The possible benefits of aggregation are to deter predation from the pooling of their chemical defenses. The nymphs are light yellowish in color with red eyes and transparent legs and antennae. The time until the next molt is three days. Feeding begins with the second instar. The second instar has black legs, head, thorax, and antennae. The abdomen is red and so are the spaces between the second, third, and fourth antennal segments. The thorax has a yellow spot on each outer side. The second instar lasts five days. The third and fourth instars differ from the second in size and an overall greenish color becoming apparent. That in my picture is the third instar. Each of these instars lasts seven days. Wing pads mark the arrival of the fifth instar. The abdomen is yellowish green with red spots on the median line. The southern green stink bug usually spends eight days as a fifth instar before the final molt to an adult.

The nymphs pierce and suck fluids from green leaves and fruits causing brownish or black spots. These punctures affect the fruit's edible qualities and decidedly lower its market value. Young fruit growth is retarded and the fruit often withers and drops from the plant. In addition to the observable damage caused by southern green stink bug feeding, the mechanical transmission of tomato bacterial spot may also result.

Giasou Nikos,
Lovely composition..
Nice details and colors.
Have a nice weekend,

Wish the focus were a bit sharper, Nikos!
Nevertheless, it is a good try and the subjects are new for TN. I don't think we have seen these Stink Bugs on TN before.

Hello Nikos,
You have photographed two beautifully marked nymphs from an attractive POV. I have never seen this species of Green Stink Bug nymphs before, so thank you for sharing this image with us.
Unfortunately the focus seems a tad bit soft and the BG has a fair amount of noise. Hope you don't mind me trying a WS.
Ron
