The flowers are across, yellow, with five pointed lobes on the corolla; they are borne in a cyme of three to 12 together. Tomato fruit is classified as a berry. As a true fruit, it develops from the ovary of the plant after fertilization, its flesh comprising the pericarp walls. The fruit contains hollow spaces full of seeds and moisture, called locular cavities. These vary, among cultivated species, according to type. Some smaller varieties have two cavities, globe-shaped varieties typically have three to five, beefsteak tomatoes have a
Plum curculio egg cavity, leaving the egg in a flap of flesh and causing a crescent-shaped scar on the outside of the fruit. Without this curved slit, eggs are killed by pressure from the growth of the host fruit. Plum curculio larvae are typically 6 to 9 mm long when fully grown, when they reach the pupal stage measuring about 5 to 7 mm; all adult characteristics are visible in this stage prior to transformation. Adult plum curculio are about 4 to 6 mm long and have a small, rough snout colored with black, gray, and brown specks. Four pairs of ridges
