Bittacomorpha clavipes, the eastern phantom crane fly, is a species of phantom crane fly in the family Ptychopteridae. The eastern phantom crane fly is not to be confused with the other phantom crane flies, Bittacomorphella jonesi and Bittacomorpha occidentalis — the pygmy phantom crane fly and the western phantom crane fly.
The eastern phantom crane fly is distributed across Eastern North America, east of the Rocky Mountains, from late spring to early fall, in the fairly dense vegetation along the shady edges of wetlands. The eastern phantom crane fly is not large. The body is approximately a half inch long and its legs are thin and black with white sheaths near the tips.
When flying, Bittacomorpha uses the wings scarcely at all, relying in great measure upon wind currents for transportation. The legs are exceedingly light, as the exoskeleton is light and delicate, and encloses practically no tissue that can serve to increase their weight. As they expose a large surface, they offer great resistance to the air without adding appreciably to the insect’s weight.
A characteristic and unique feature of the family is a lobe at the base of the haltere called the... Wikipedia →

Rare
Under 5% of wildlife watchers report an Eastern Phantom Crane Fly sighting in Boston on a given day, based on 32 verified sightings from GBIF citizen-science data. It is the 342nd most-seen of the 1200 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
May and June
In those months about 10% of wildlife watchers report an Eastern Phantom Crane Fly in Boston on a given day, against under 5% in July to April, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Eastern Phantom Crane Fly sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 6 cities where we can rate Eastern Phantom Crane Fly sightings, Boston has the highest daily chance: under 5%. Next come Washington (United States, under 5%) and Montreal (Canada, under 5%).
Same order: Diptera
The closest relatives of the Eastern Phantom Crane Fly that you can see in Boston (order Diptera, Flies) are Margined Calligrapher (about 20%), Eastern Calligrapher (about 20%) and Transverse-Banded Flower Fly (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Eastern Phantom Crane Fly is recorded against all the insects logged in Boston (32 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.
