hi all ı have sent before yellow laydbug this one is other one Thea vigintiduopunctata .have a nice days.

Coccinella septempunctata
(Coleoptera: Coccinellidae)
Sevenspotted Lady Beetle
The sevenspotted lady beetle, repeatedly introduced to North America from Europe for the biological control of aphids, was established in the early 1970s in New Jersey, apparently from an accidental introduction. It has since spread naturally or been introduced to many northeastern and north central states. C. septempunctata may be a more effective predator than some native lady beetle species, displacing them in some areas.



Appearance
Comparatively large (7-8 mm) with a white or pale spot on either side of the head. The body is oval, and has a domed shape. The spot pattern is usually 1-4-2, black on the orange or red forewings. Lady beetle larvae are dark and alligator-like with three pairs of prominent legs, growing to 7-8 mm in length. Eggs are spindle shaped and small, about 1 mm long.

Habitat (Crops)
Aphid infested crops, including potatoes, legumes, sweet corn, alfalfa, wheat, sorghum, and pecans.

Pests Attacked
Reported prey include pea, cowpea, green peach, potato, corn leaf, melon aphids, and greenbug.

Life Cycle
Adults overwinter in protected sites near the fields where they fed and reproduced. In spring, emerging beetles feed on aphids before laying eggs. Females may lay from 200 to more than 1,000 eggs over a one to three month period commencing in spring or early summer. Eggs are usually deposited near prey such as aphids, often in small clusters in protected sites on leaves and stems. The eggs are small (about 1 mm) and spindle-shaped.

C. septempunctata larvae grow from about 1 mm to 4-7 mm in length over a 10 to 30 day period depending on the supply of aphids. Large larvae may travel up to 12 m in search of prey. A second generation may appear about a month later. The pupal stage may last from three to 12 days depending on the temperature.

In the northeastern United States, there are one to two generations per year before the adults enter winter hibernation. Development from egg to adult may take only two to three weeks, and adults, most abundant in mid- to late summer, live for weeks or months, depending on the location, availability of prey, and time of year.

Conservation
C. septempunctata is spreading to new areas each season. Conservation can best be accomplished by following integrated pest management guidelines as outlined in the tutorial of this guide.

Pesticide Susceptibility
Tolerance to some pesticides at recommended application rates is likely. Overwintering adults may be less susceptible than active adults and larvae.

i saw this picture as a thumbnail in the main gallery and thought that it would be a very nice picture, it is indeed a great picture. i really love the sharpness of the ladybug, and the nice yellow that compliments the background and the 'leaf'. a really nice picture.
well done!

Hi Ridvan,
I love the DOF in this shot and the amount of BG is very affective.
Great colours and decent composition.
TFS Joey

A yellow Ladybird is a rarity in my opinion, Ridvan.
This is a fine image from good point of view. The diagonal placement of the subject looks appealing in this composition.
I shot a different coloured Ladybug last year in India, but the two shots of it I have are rather out of focus and I have not been able to share them here on TN.
All the best.
Ram

Merb Ridvan cok guzel olmus composition iyi aksamlar selamlar Necip

hello Ridvan,
That's a nice picture of this yellow ladybug, which you caught very sharply. I just think that it is not a Coccinella septempunctata, because it has obviuosly more than seven (septem) dots. May be something like 22 punctata, but I'm not a specialist.
best regards
Anne

Hola Ridvan,
Excelente macro de este pequeñísimo insecto, nitidez, luminosidad y detalle son muy buenos. Saludos

Hi Ridvan.
Amazing close-up, may be aperture is fast a bit and DOF is shadow. However, shot is composed perfectly. I also like the details of the bug, excellent light and pleasant colour palette. Your note is great. Thank you. My best wishes and TFS.

Hello Ridvan,
the small ladybird is shown very sharp and in its beautiful natural colours. A well-focused picture, even the tarsal claws are nicely visible. I would like to include this ladybird in my THEME on Coccinellidae. Is that o.k?
Its name, however, is
- Thea vigintiduopunctata (with 22 dots)
Best wishes, Peter
P.S. No time to respond earlier!
