[2][3][4][5][6] A study published in 1987 showed the distribution of J. haematoloma and "revealed the close correspondence of records for the bug with the ranges of the soapberry plants that serve as the insects native hosts.
Outside of the United States, J. haematoloma is found south through Central America and the West Indies to Colombia and Venezuela.
[8][9] Although native to the New World, the discovery of J. haematoloma populations in Taiwan in 2012 marked the first finding of the species and genus in Asia.
Significantly, the Flamegold was colonized by J. haematoloma, though its capsules are smaller and the seeds less deeply embedded than in the balloon vine.
In a seminal paper published in the scientific journal Genetica in 2001, it was shown evolution had taken place in this colonizing population of J. haematoloma on the Flamegold in a period of only a few decades.
