Field Notes

Description:

The large milkweed bug, Oncopeltus fasciatus, is colored orange-red and black. It has a long proboscis and is a piercing sucking insect. It feeds on the seeds, leaves and stems of milkweed (Asclepias). It is found in small groups on milkweed often on the stems, leaves and on the seed pods. The bodies of milkweed bugs contain toxic compounds derived from the sap which they suck from milkweed. Milkweed bugs are true bugs (Hemiptera) .

Habitat:

Miller Springs Park is a 360-acre park located below Belton Lake, on the Leon River, in Bell County, Texas. It contains diverse riparian terrain, including limestone bluffs, estuarial wetlands, mountain cedar hilltops, and riverside cottonwood stands. Numerous trails traverse prairie-like open spaces and forests of native cedar elm, live oak, and red oaks. Recent floods have created a new canyon that reveals numerous layers of sedimentary rock and fossils. Area wildlife includes white-tail deer, red foxes, coyotes, black squirrels, armadillos, and about 200 species of birds in the course of the year.
