    False Chinch Bug - (Nysius raphanus)

    Pervasive pests like the False Cinch Bug roam from crop to crop, damaging new leaf growth and plant health wherever they land.

    Staff Writer (6/13/2017): False Cinch Bugs fly to their food sources, sometimes miles apart. Adults pierce plant stems and drink the juices from the plant, depriving it of food and water. False Cinch Bugs prefer to eat alfalfa, radish leaves and mustard greens, but they will move to other field crops like potatoes and grains once their first food source has been harvested. They will then return to fields that have recovered and feed again. The damage from feeding takes days to few weeks to appear and can include things like leaf wilting, leaf curling or the appearance of leaf burn.

    False Cinch Bugs are fast breeders and eggs take only a few days to hatch. Nymphs mature into reproducing adults in less than a month. This means many generations of bugs can live at the same time, feeding in the same field. Mid-summer sees populations at their largest size, which is when many crops are reaching peak growth for harvest. They overwinter in both life stages, taking nutrition from cold-weather crops and wild plants like sages. Look for adults in the cooler parts of the day like dawn and dusk. The hot afternoon sun drives them to the ground for shade cover. In dry, hot spells during the summer, clusters may see cooler temperatures inside buildings. They are not dangerous to people: they don't bite or destroy interior dwellings. They are a nuisance, but usually a short-lived one, lasting only a week or so indoors, but removing indoor populations using a vacuum is recommended over pesticide use.

    BUGFINDER: What Kind of Bug is This...
    BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
