Is it poisonous if bitten by a dragonfly?

Being bitten by a dragonfly is not poisonous. If local swelling and congestion occur, an allergic reaction may have developed. It is recommended to seek medical examination and treatment promptly to avoid delaying the condition.

Dragonflies are among the most common insects in the world, primarily living in environments such as ponds, fields, and riverbanks. When encountered in the wild, it's best not to attempt catching them, as they may bite. Dragonfly bites are non-venomous because the insects themselves are not toxic, making transmission of disease highly unlikely. However, if accidentally bitten, an allergic reaction may occur, resulting in redness, swelling, or even discharge. The wound can first be cleaned with iodophor or alcohol. Then, visit a professional dermatology department for diagnosis. Once the cause is confirmed, under medical guidance, antihistamines or toxin-antagonizing medications such as loratadine tablets or benactyzine tablets can be used. It's important to drink plenty of water to promote metabolism. Generally, recovery to a normal state takes about 1–2 weeks.

There is no need to worry about being infected with diseases such as rabies from a dragonfly bite. Certain species of dragonflies contain biologically active substances and can be used as medicinal materials. Their larvae and pupae are nutritionally valuable and edible, while visually striking dragonflies can be kept for ornamental or collection purposes.
