Subject: Bee? Fly? Friend or Foe?
February 27, 2015 8:47 am
I’m hoping someone can help me identify this bug. I’ve found 3 of them thus far. They appear to have been created in my large pot of amaryllis that I drag indoors and outdoors each year. Last fall, I quit watering the large pot and stored it in cool, darkish conditions (unheated garage) for about 4 months. After moving it to a warm sunny location – these gentle creatures are making their appearance. Google hasnt helped. Thanks for any information you can share!

Dear Green thumb-newbie apridarist,
This is a Narcissus Bulb Fly, Merodon equestris, which we identified on BugGuide, and though they are generally associated with daffodil and narcissus bulbs, according to the North Carolina State University Insect and Related Pests of Flowers and Foliage Plants site: “Distribution -The narcissus bulb fly occurs wherever narcissus are grown throughout the United States. This pest was introduced from Europe in about 1869. Host Plants -The narcissus bulb fly has been reported to infest amaryllis, daffodil, Galtonia, Flanthus, hyacinth, Iris, lilies, Leucofum, Narcissus, Scilla, tulips, and Vallota. Damage -The center of the bulb is hollowed out and the flower bud is destroyed. Many infested bulbs rot away although some survive to send up a few scrawny grasslike blades the following year.”
