Rhopalomyia lobata is a species of gall midges, insects in the family Cecidomyiidae. The galls form on stems and buds of Euthamia graminifolia the grass-leaved goldenrod . The species ranges from Florida to Mississippi, north to Oregon, New England and most of Canada.

Galls and Biology

The galls, which have multiple chambers, are created in both the apical and lateral buds. Some of these galls can be found in clusters near the shoot tip or in adjacent lateral buds. The spongy mass at the base of the gall gradually grows to a final size of 6 cm in diameter. The leaves encircling the mass are wider than the typical leaves of the plant, but they start to become loose in the second week of June. The whitish tissue is then visible, and there are 5-35 larval chambers embedded within. During late June to mid-July, the adults emerge, exposing the fleshy core of the gall. After the midges emerge, the gall turns black, and dry galls are present on the plants for several weeks. [1] [2] [3]

<span class="mw-page-title-main">Cecidomyiidae</span> Family of flies

Cecidomyiidae is a family of flies known as gall midges or gall gnats. As the name implies, the larvae of most gall midges feed within plant tissue, creating abnormal plant growths called galls. Cecidomyiidae are very fragile small insects usually only 2–3 mm (0.079–0.118 in) in length; many are less than 1 mm (0.039 in) long. They are characterised by hairy wings, unusual in the order Diptera, and have long antennae. Some Cecidomyiids are also known for the strange phenomenon of paedogenesis in which the larval stage reproduces without maturing first. In some species, the daughter larvae consume the mother, while in others, reproduction occurs later on in the egg or pupa.

<i>Asphondylia</i> Genus of flies

Asphondylia is a cosmopolitan genus of gall midges in the family Cecidomyiidae. All species in this genus induce galls on plants, especially on flowers and flower buds. There are over 300 described species in Asphondylia, with many more likely to be discovered and described, especially in the southern hemisphere.
