With the website currently down and no questions to answer, we have been strolling through the canyon briskly every morning. We have been noticing several species of insects that we occasionally get letters regarding, and others that are just plain interesting. We decided to return with our digital camera and photograph some of the above. Here are some Harlequin Bugs, Murgantia histrionica. They are small stink bugs, about 1/4 inch long. They are variegated black, red, and white with a reddish or light colored + on the scutellum. These bugs are occasionally seen in the garden where they feed on cabbage, sweet alyssum and related plants of the family Brassicacaea, but in the canyon and vacant lots, they prefer wild mustard. According to Hogue: “Mating pairs are often present. The male illicits copulation by tapping the female’s antennae and body with his antennae.” Females lay several sets of 5-12 eggs that look like black and white striped barrels.
(06/26/2004) Copulating Harlequin Bugs will eventually lay eggs. The female places one or two rows of from usually 5-12 eggs neatly on twigs. The eggs look like black and white striped barrels. Here are some freshly layed eggs on anise.
