Wood affected by woodworm. Signs of woodworm usually consist of holes in the wooden item, with live infestations showing powder (faeces), known as frass, around the holes.. The size of the holes varies, but they are typically 1 to 1.5 millimetres (5 ⁄ 128 to 1 ⁄ 16 in) in diameter for the most common household species, although they can be much larger in the case of the house longhorn beet
Many flower-dwelling species bring benefits as pollinators, with some predatory thrips feeding on small insects or mites. In the right conditions, such as in greenhouses, invasive species can exponentially increase in population size and form large swarms because of a lack of natural predators coupled with their ability to reproduce asexually ...
The eggs hatch after some three weeks, each producing a 1 millimetre (0.039 in) long, creamy white, C-shaped larva. For three to four years the larvae bore semi-randomly through timber, following and eating the starchy part of the wood grain, and grow up to 7 millimetres (0.28 in). They come nearer to the wood surface when ready to pupate.
Flowers are pale yellow, tubular, and clustered in spherical bent-down heads (capitula), which are in turn clustered in leafy and branched panicles. Flowering occurs from early summer to early autumn; pollination is anemophilous. The fruit is a small achene. Seed dispersal occurs by gravity. [5]
The larvae of a number of Ptinidae species tend to bore into wood, earning them the name "woodworm" or "wood borer". Several species are pests, causing damage to wooden furniture, house structures, tobacco, and dried food products.
They come in every size from tiny pom-pom shapes to flowers as big as a dinner plate. They're perennial in zones 8 and warmer, but dig up the tubers in colder regions to save for replanting in spring.
Of the quarter million species of beetles, some adults damage books by eating paper and binding materials themselves. However, their larvae do the most damage. Typically eggs are laid on the book's edges and spine. Upon hatching, they bore into, and sometimes even through, the book. [3] Drugstore beetle on a human finger
