#1620 - Musgraveia sulciventris - Bronze Orange Bug
Photo by Kerri Faull.
I’m a bit surprised that I haven’t covered these guys, or apparently anything from their entire family, before. They’re quite a common backyard pest of citrus in Eastern Australia, and the Tessaratomidae are large and often colourful bugs (although the heads are disproportionately small).
One lemon tree can be carrying hundreds, if you don’t go out and pluck them off by hand. Gloves and probably a face mask are a must - they defend themselves by spraying alkanes, cimicine and aldehydes.
Bronze Orange Bugs grow up to an inch long, but start of as translucent, very flat green nymphs, and grow to be bright orange nymphs. The common name, however, refers to the colour of the adult, and their frequent diet.
Photo by William John, with the note “Can you smell a stinkbug? I asked the wife. Brushed my hair and this stinky little guy drops onto the floor. Serves me right for pinching some lemons off the neighbours tree.”

#1630 - Lyramorpha rosea - Lychee Bug/Litchi Bug
Photo by Vali Audet, on a Tuckeroo (Cupaniopsis anacardioides), on the Central NSW Coast.
Photo by Grant Webster at Fingal Bay, NSW.
Despite the common name, Lyramorpha bugs are rare visitors to Lychee and Longan Trees, and never in sufficient numbers to be a problem. They will feed on the sap of a wide range of other plants, including suburban roadside trees, which can be a problem given their pungent chemical defences.
Like the related Bronze Orange Bug, this Tessaratomid starts off very flat and colourful (bright red, or bright orange, with electric blue trim, depending on species), and matures into an adult with a tiny, tiny head. Females will gaurd their young for at least the first two instars.
