Bactrocera cucurbitae
In 3 days ~30% in a week ~60%
Zeugodacus cucurbitae, the melon fly, is a fruit fly of the family Tephritidae. It is a serious agricultural pest, particularly in Hawaii. The adult melon fly is 6 to 8 mm in length. Distinctive characteristics include its wing pattern, its long third antennal segment, the reddish yellow dorsum of the thorax with light yellow markings, and the yellowish head with black spots.
The egg is elliptical, about 2 mm long, and pure white. It is almost flat on the ventral surface, and more convex on the dorsal. Eggs are often somewhat longitudinally curved. The larva is a cylindrical-maggot shape, elongated, with the anterior end narrowed a somewhat curved ventrally. It has anterior mouth hooks, ventral fusiform areas and a flattened caudal end. Last instar larvae range from 7.5 to 11.8 mm in length.
The puparium ranges in color from dull red or brownish yellow to dull white, and is about 5 to 6 mm in length. Development period from egg to adult ranges from 12 to 28 days. The female may lay as many as 1,000 eggs. Eggs are generally laid in young fruit 2-4mm deep, but are also laid in the succulent stems... Wikipedia →

With luck
About 10% of wildlife watchers report a Melon Fly sighting in Dhaka on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 74th most-seen of the 92 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
March
In that month about 40% of wildlife watchers report a Melon Fly in Dhaka on a given day, against under 5% in January–February and April–October, the lowest months. That is one of Dhaka's driest months, with about 50 mm of rain against 440 mm in July.
Yes
Of the 3 cities where we can rate Melon Fly sightings, Dhaka has the highest daily chance: about 10%. Next come Hyderabad (India, about 10%) and Bengaluru (India, under 5%).
Same order: Diptera
The closest relatives of the Melon Fly that you can see in Dhaka (order Diptera, Flies) are Yellow-Shouldered Hover Fly (about 20%), Marmalade Hover Fly (about 10%) and Bathroom Moth Fly (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Melon Fly is recorded against all the insects logged in Dhaka (5 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
