common name: a fruit fly
scientific name: Anastrepha ocresia (Walker) (Insecta: Diptera: Tephritidae)
Anastrepha ocresia (Walker) is one of six species of fruit flies of the genus Anastrepha which occur in Florida or which have been established in Florida at some time. This West Indian species has been collected in Florida only in the Keys of Monroe County where it has been found sparingly; it has not been found in Florida since 1936. There is
a distinct possibility that this species has not survived in Florida. It is not
considered to be of economic importance anywhere within its range.

Recorded from the Florida Keys, from Key Largo to Key West, as well as Cuba, Puerto Rico, Jamaica, and Hispaniola. The Florida records are from Rock Harbor, Key Largo Key, July 7, 1936, and from Key West, March 28, 1936. Except for the holotype female (British Museum), the species has not been collected on
Jamaica. Other specimens are from the Isle of Pines, the eastern and western tips of Cuba, and Santo Domingo City, Hispaniola. A specimen which subsequently was described by Loew as Trypeta tricincta, a synonym of A. ocresia (Walker), was collected aboard ship 60 miles northwest of St. Nicholas, Haiti, but its origin is unknown.
distribution map
Small orange brown fly with patterned
wings, banded abdomen, and somewhat long ovipositor sheath. The wing pattern is
predominantly dark brown; distal arm of V band present, separated from proximal
arm, or narrowly joined to side of latter at M1+2; proximal arm of V
band usually extending forward to vein R4+5 but not joined to S band;
costal and S bands connected, the hyaline spot usually not touching vein
R4+5; wing 6.6 to 7.5 mm long. Thorax orange brown, with pale- yellow
and black markings, black markings consisting of a median spot lying in a
brownish band on scutoscutellar suture, acute anteriorly, usually notched
posteriorly, and metanotum except for a narrow median stripe. Macrochaetae
black; pile pale yellowish. Abdomen orange brown, with transverse brownish-black
bands on tergites 2-4 basally, not reaching lateral margins, and those on
tergites 3-4 narrowed or broken medially.
adult female
Ovipositor sheath of female 3.6 to 3.9 mm long; ovipositor approximately 3.3 mm long, stout, with many fine, blunt teeth on a little more than posterior half.

The life history of Anastrepha
ocresia has not been ascertained.
