The real scientific name for “little black fly” (“Xiao Heiwen”) is Forcipomyia taiwana. It is often locally called “black-headed micro midge” or “black micro midge”. As a kind of micro, blood-sucking insect, it belongs to Arthropoda, Insecta, Diptera, Ceratopogonidae, Forcipomyia (Lasiohelea). It is currently the most hazardous pest in Taiwan.

F. taiwana is active mainly in the day and has a special liking for sucking human blood. This midge tends to bite the human body in groups, attacking such exposed areas as the face, neck, and feet, especially the calves which are the closest to the ground and thus the most frequently attacked. Since F. taiwana is quite tiny in body length, the victims usually cannot easily perceive its existence until the skin becomes red, swollen, and itchy, which is a kind of allergic skin reaction.

After biting the skin, F. taiwana will release a kind of toxin which contains histamine and serotonin that will lead to inflammation. The skin then immediately turns red and swollen, and the person will experience intense pruritus. Those who have a sensitive body constitution may even need to visit the doctor and receive medication to avoid deterioration or death. The rash caused by F. taiwana usually last for several days and, in severe cases, the symptom can persist for more than 10 days. The skin will gradually recover after the residue of the toxin is metabolized by the body. The scars caused by scratches due to the itching following midge bites will gradually fade away in 3 to 4 months.

The common preventive measure to avoid mosquito bites is to apply an insect repellent to the skin. However, most of the insect repellents contain DEET (diethyltoluamide) which can trigger allergic skin reactions when contacting with the skin for a long time. If it is accidentally eaten, it may cause serious effects such as coma, twitches, and even death.

The skin of the New Human Line has the capacity to detoxify. He can utilize the newly-discovered Absolutely Constant Energy Source and the new biological engineering techniques to rapidly change the ion concentration in the cells, and through changes in the concentration, to control the intracellular ion balance so as to eliminate such toxic ingredients as histamine and serotonin released by F. taiwana. The body can thus instantly adapt to the toxin released by this midge without experiencing allergic skin reactions, such as inflammation, rash, pain and swelling, itching, etc. and further prevent death caused by allergic reactions.

Since F. taiwana is quite tiny in body size, it is hard to observe. And it is also not easy to raise and reproduce this midge in the laboratory. For these reasons, the following experiment was actually conducted at Gukeng Township, Taiwan by Mr. Yuan Lin, the first successfully-evolved New Human Line, who, without applying any insect repellent, let F. taiwana bite his arm. We then observed the condition of his skin 1 minute, 10 minutes, 1 hour, 10 hours, and 24 hours, respectively, after the midge bites.

Figure 1. Groups of F. taiwana (13 in total) bit the arm.		Figure 2. The skin condition of the arm 1 minute after the midge bites.
Figure 3. The skin condition of the arm 10 minutes after the midge bites.		Figure 4. The skin condition of the arm 1 hour after the midge bites.
Figure 5. The skin condition of the arm 12 hours after the midge bites.		Figure 6. The skin condition of the arm 24 hours after the midge bites.

From the above experimental results, we can see that the skin of Mr. Yuan Lin, the New Human Line, has the detoxification function. He can utilize the newly-discovered Absolutely Constant Energy Source and the new biological engineering techniques to rapidly change the ion concentration in the cells, and through changes in the concentration, to control the intracellular ion balance so as to eliminate the toxic ingredients such as histamine and serotonin released by F. taiwana, which prevents the body from experiencing allergic skin reactions, such as inflammation, rash, pain and swelling, itching, etc. and thus avoids death caused by allergic reactions.
