These soon hatch into legless white maggots which after 2 to 5 days of development transform into reddish-brown pupae, about 8 mm (0.3 in) long. Adult flies normally live for 2 to 4 weeks but can hibernate during the winter.
The American Community Survey (ACS) is a 21-page questionnaire generated by the US Department of Commerce under the auspices of the US Census Bureau. Funded by tax dollars, the lengthy questionnaire is mailed to 2% of the US population annually.
Although the questions used in the ACS are very similar to those included on the long form used in the 2000 decennial census, there are some important differences between the two surveys. Because ACS data are collected continuously, they are not always comparable to data collected from the decennial census.
