BIOLOGY OF THE TERMITES OF THE EASTERN UNITED STATES. 69 
W. D. Hunter states ¢: 
Termes flavipes K. is not uncommon in Texas, where swarms occur ordinarily 
during the early part of the season. In 19i1, however, the insect did not come into 
notice until about the middle of October [lucifugus?]. At that time much more than 
usual numbers were to be seen throughout the State. 
Often several swarms emerge from the same colony in the same 
year. At McDonogh, Md., in April, 1913, according to a correspond- 
ent, sexed adults swarmed from the woodwork of a house, the beams 
being honeycombed. A very large swarm issued on April 6, another 
on April 13, a third on April 18, and a fourth swarm issued April 25, 
comprising in all four distinct swarms. In size, however, the first 
swarm, from my observations, is usually the largest. (Fig. 12.) 
Leucotermes virginicus swarms during the forenoon in the vicinity 
of Washington, D. C., usually one month later than flavipes, or in 
early June. However, on August 11, 1913, at Falls Church, Mr. 
William Middleton observed a large swarm to emerge from a small 
chestnut corner stake which was set in the ground. The colony, 
which was not large, swarmed at 12.30 p.m. 
Leucotermes lucifugus, according to Heath,? swarms “* * #* 
at different times between the months of Octoberand April * * *.” 
“Tt usually takes place about 11 a.m.” 
During the early part of May, 1909, sexed adults of Leuwcotermes 
sp. (probably flavipes) were observed by the writer emerging in great 
numbers from the ground in the fenced yard of an old house located 
in a pine grove near Woodville, Tyler County, Tex. The swarm 
occurred in the forenoon of a warm, sunny day. 
The following notes were made by members of the branch of 
Southern Field Crop Insect Investigations, in charge of Mr. W. D. 
Hunter: 
On September 12, 1910, a light shower fell, and before the rain had entirely stopped 
the air was full of flying termites; this lasted one hour. On December 16, 1910, there 
was a swarm [/ucifugus] at Dallas, Tex. After arain at Dallas, October 13, 1911, there 
was a swarm; another rain brought them out on October 16, 1911. On October 18, 
1912, there were swarms of termites at Dallas, following a two-day’s rain. 
It will be seen from the foregoing that reliance, in the determination 
of species, can be placed on the dates of swarming, since the species 
flavipes never swarms in the fall in the eastern United States. 
Apparently rainfall has no influence on the time of swarming, as is 
the case in Texas.
