![]() ![]() It’s important to take a proactive approach and get the upper hand.Ĭhemical control is effective on the nymph stage by applying pesticides like carbaryl, bifenthrin or permethrin. If you have a no-care attitude, you might want to rethink that logic because each surviving female can lay up to 400 eggs that will emerge next March. The eggs are the overwintering stage and lie in wait for suitable soil temperatures in the spring. Each female grasshopper deposits three to five egg masses, called a pod, and each pod has about 30 to 80 eggs. The male guards the female as she deposits eggs two inches down into the soil and surrounds them with a frothy mass. In mid-summer, females seek higher ground and begin laying eggs in slightly moist soils. July and August are the months that we see the highest numbers of adult grasshoppers. They resemble miniature grasshoppers and molt five times before becoming an adult. In north Florida, eggs hatch in mid to late March and young nymphs crawl up out of the soil, moving in groups, to feed on suitable plant material. The good news is that there is only one generation per year. Some are brownish red but they still have the characteristic stripes. ![]() Nymphs are usually black with one or more yellow, orange, or red stripes and the front legs and sides of the head are red. The immature stage is referred to as a nymph and looks very different from the adult grasshopper. There is a darker form of the adult lubber that is mostly black with a few dull yellow marks. The front pair of wings is yellow with numerous black spots and the hind wings, usually hidden, are bright red/rose with a black border. Although not capable of flying, they have 2 pairs of wings. There are several color variations throughout the state of Florida but they are typically dull yellow with black spots and markings. At maturity, males and females reach 2 1/2 to 3 inches long, respectively. The adult eastern lubber grasshopper is one of the most intimidating insects due to its large size and distinct colors. Some of our daffodils and amaryllis have been chewed down to the ground. The young are more voracious feeders than the adults and will strip plants of leaves or chew obvious holes before moving on to the next leaf. Once you have them in your landscape, they are almost impossible to eradicate.Īlthough they will occasionally feed on young fruit, lubber grasshoppers are predominately leaf feeders. These critters have been a problem in our office landscape for more than a decade and they are busily feeding on a wide list of plants including daylilies, daffodils, plumbago and amaryllis. ![]() Extensive damage has been recorded on citrus, vegetable crops, and landscape plants. They are found throughout Florida and extend north into central North Carolina and west into eastern Texas. Most grasshoppers don’t reach populations that cause serious damage to agricultural crops and landscape plants, but the eastern lubber grasshopper (Romalea guttata) is one of the exceptions. Now is the time to target the control of these pesky lubber grasshoppers while they are young and gregarious. They’re back! Small lubber grasshoppers appear to bubble up from the soil forming a black mass that moves in groups aand consumes plants along the way. ![]()
