On a visit to Lick Creek Park in College Station, Texas on May 4, 2010, I observed an unusual sight on the mustang grape plant growing along the Iron Bridge Trail. The plant was infested with small, two-winged fly larvae, which had caused irregular swellings or galls to form on its leaves and stems. These galls, known as Grape Tomato Gall, were a mass of wrinkled, red tissue that had grown around the feeding sites of the fly larvae. The galls were quite numerous, covering much of the plant's surface and giving it a distinctive, bumpy appearance. This phenomenon is caused by the larvae of the Lasioptera vitis fly, which lays its eggs on the grape leaves and stems, and the resulting galls provide a unique and interesting feature of the plant's growth. – generated by AI

The image shows a close-up view of the Grape Tomato Gall on a Mustang Grape vine.

This gall is caused by Lasioptera vitis, a small two-winged fly that lays its eggs on the plant. The larva hatches from these eggs and burrows into the stem, causing abnormal growth to form around it.

The gall has irregular swellings produced by the larva's presence and appears to be reddish-pink in color with clusters of green berries growing out from them.

There is a web-like substance visible on some parts of the gall that may have been spun by an insect or spider. The background of this image is black, suggesting it was taken using a dark-field microscope or macro lens.

Overall, this image provides a detailed view of the Grape Tomato Gall and its effects on the Mustang Grape vine. – AI vision

La galerita del tomate de la vid, Lasioptera vitis (masa de hinchazones irregulares producidas por la larva de una pequeña mosca de dos alas), en el sendero Iron Bridge del parque Lick Creek. College Station, Texas, 4 de mayo de 2010. La imagen muestra una vista detallada de la galerita del tomate de la vid en una vid de uva mustang. Esta galerita es causada por Lasioptera vitis, una pequeña mosca de dos alas que pone sus huevos en la planta. La larva eclosiona a partir de estos huevos y se abre paso hacia el tallo, provocando un crecimiento anormal para formarse alrededor de ella. La galerita presenta hinchazones irregulares producidas por la presencia de la larva y parece ser de color rosado-pink con racimos de bayas verdes creciendo desde ellos. Hay una sustancia similar a una red visible en algunas partes de la galerita que puede haber sido tejida por un insecto o araña. El fondo de esta imagen es negro, lo que sugiere que fue tomada usando un microscopio de campo oscuro u objetivo macro. En general, esta imagen proporciona una vista detallada de la galerita del tomate de la vid y sus efectos en la vid de uva mustang. – Spanish translation
