#1833 - Agonoscelis rutila - Horehound Bug

Spotted at the Rockingham Environment Center, advertising their presumably unpleasant taste, probably derived from the highly aromatic plants they feed on. 

This Pentatomid is native to Australia, but is so overly attracted to the highly invasive and noxious (in both senses of the word) weed Horehound (Marrubium vulgare) that we don’t know what the original host plant was. Given that other known hosts for the bug include Lavender (Lavandula), as here, and Salvia (S. divinorum), it was probably something in the Lamiaceae. 

Horehound is native to many parts of Eurasia and north Africa, but is now found in most parts of the world. It was introduced to Australia as a medicinal plant, supposedly useful against respiratory complaints, but there’s no evidence that it’s actually useful for any such purpose. 

Unfortunately, despite the Horehound Bug’s enthusiastic appetite for Horehound, it doesn’t appear to be very useful as a biological control - and the reason appears to be another species actually introduced as a biocontrol agent, the egg parasitoid wasp Trissolcus basalis. This Platygastrid wasp was originally introduced to Australia in 1933, to control the Green Vegetable Bug Nezara viridula, another Pentatomid species. Not only is the wasp highly territorial, chasing off other parasitoids from whatever area she has claimed as her turf and reducing the number of Nezara eggs that actually get parasitised, it also targets the eggs of at least 25 other species of Pentatomid Bug, including Predatory Shield Bugs that would actually protect crops from other pests. So the wasp’s failures as a biocontrol include making the Horehound Bug fail as a biocontrol. 

(That said, the horehound clearwing moth (Chamaesphecia mysiniformis) and the horehound plume moth (Wheeleria spilodactylus) are showing hopeful evidence as biocontrols of the weed.)

*nezara voice* today i will cause problems on purpose

Is there any reason she’s tied up unlike other random rare mobs in caves?

#2383 - Nezara viridula - Southern Green Stink Bug

Not pictured - the praying mantis off to the left that I didn't even notice until I checked the photos later.

AKA Cimex smaragdulus, Cimex viridulus, Nezara approximata, and Nezara aurantiaca, southern green stink bug or southern green shield bug.

A plant-feeding Pentatomid that probably originated in Ethiopia, but can now be found across the world. A serious pest of legumes, but the diet is much wider than that. Adults are usually a uniform green (or brown in winter), but some have white or yellowish front margins on the head and the thorax, and a very rare morph is uniformly orange or yellow.

When ready to mate N.viridula produce a 100 Hz vibration to communicate with any other Nezara on the plant. The female lays 30 to 130 eggs at a time. The larvae stay close together until their third moult, probably to pool their chemical defenses.

The Shield-bug nymphal parasitoid wasp Aridelus rufotestaceus arrived in Auckland at some point before 2010, but also attacks other introduced and endemic shield bugs. The Green vegetable bug egg parasitoid wasp Trissolcus basalis was deliberately introduced in 1949 to control Nezara viridula but is similarly indescriminate.

Pohokura, North Island, New Zealand.
