Explanation of Names

Anastrepha ludens (Loew 1873)

Size

7-11 mm, ovipositor 3.35–4.7 mm(1)

Identification

Notable for the female's long ovipositor and sheath relative to its body size(1)

Eyes are beautiful iridescent green with other colors appearing depending on the angle and intensity of light. Body is mostly yellowish; dorsal surface of thorax browner with longitudinal yellow stripes. Wings marbled with yellowish bands.

Range

native to Mesoamerica; adventive in our area (s US: southmost Texas only as of 2012, historical records from CA and FL)(1)

Habitat

Mainly agricultural, but anywhere with fruit trees

Food

All varieties of citrus except lemons and sour limes are attacked. Grapefruit is the preferred host, with oranges second. Pear, peach and apple are preferred among deciduous hosts. Full list of hosts(1)

Life Cycle

Adult females may be very long-lived, up to 11 months, and highly fecund, laying 1,500 eggs or more. Males appear to be able to survive as long as 16 months.(1) Eggs hatch in 6-12 days. Larval stage lives in fruit pulp and lasts 3-4 weeks, leaving fruit to pupate in soil.

Remarks

earliest record in our area: TX 1927(1)

USDA releases sterile flies to maintain "fly-free zones" in Texas, Mexico, and California. Sterile flies have an orange/pink dye spot on their forehead.
