LYGUS BUG

The genus Lygus includes over 40 species of plant-feeding insects in the family Miridae. At one time, nearly 200 species were classified as genus Lygus, but most of those have since been reclassified into new or existing genera. The term lygus bug is used for any member of genus Lygus. The more well-known lygus bugs are those that have agricultural impacts. Some lygus bugs are very serious agricultural pests.
The insects appear as small oval creatures. Adult lygus are approximately 3 mm wide and 6 mm long, colored anything in a range from pale green to reddish brown or black. The bugs can be solid shaded or mottled, and have a distinctive triangle or V-shape on their backs. Adults are capable of flight, and will often thus escape when approached. Nymphs are wingless, and being light green in color, are often mistaken for aphids. However, lygus nymphs have harder shells, are typically more active, gain spots as they age, and lack aphid abdominal tubes.
Lygus bugs are known for their destructive feeding habits - they puncture plant tissues with their piercing mouthparts, and feed by sucking sap. Both the physical injury and the plant's own reaction to the bugs' saliva cause damage to the plant. The females insert their eggs directly into the plant tissues using piercing ovipositors, and the newly emerged nymphs are voracious consumers of plant tissue juices. Signs that a plant has been attacked by lygus bugs include discoloration, deformation of shoots and stems, curling of leaves, and lesions on the plant tissues.
• The tarnished plant bug (Lygus lineolaris) feeds on over half of all commercially-grown crop plants, but favors cotton, alfalfa, beans, stone fruits, and conifer seedlings. This bug can be found across North America, from northern Canada to southern Mexico.
• The western tarnished plant bug (Lygus hesperus) is a very serious pest of cotton, strawberries, and seed crops such as alfalfa. In the state of California alone the bug causes US$30 million in damage to cotton plants each year, and at least US$40 million in losses to the state's strawberry industry.
• The European tarnished plant bug (Lygus rugulipennis) is distributed throughout Europe, where it will feed on over 400 types of crop plant from peach trees to wheat to lettuce.
Some methods of biological pest control have proved useful against lygus bugs. For example, wasps of the genus Peristenus are parasitoids of lygus bugs; an adult wasp will inject an egg into a lygus nymph, and once the egg hatches the wasp's larva will consume the nymph from the inside out.

Hi Ram,
Excellent composition and very nice colour rendition but I think something went awry with the focussing. The leaf is pin sharp but the insect is rather soft. I think the camera decided to go for the leaf.
All the same you more than made up for that with your usual exhaustive note

Hi Ram.
Very well composed and beautiful macro shot. You managed to separate foreground and BG by the leaf excellently. I like great sharpness and details of the leaf and bug and very nice lighting of foreground. BG is perfectly blurred, colourful and impressive. Superb done picture in wonderful green key. TFS and my best regards,
Alexei.

Hola Ram.- Una bella foto de este Insecto, el color de sus alas se aprecienan con detalle. Luis52.

Hello Ram,
Nice seeing Lygus bug from your hometown. Relatives of this bug also live here. The head is a bit soft, may be because of bug movement. A nice picture to see though.
