Xylotrechus

* Se Systematisk inndeling

***Xylotrechus*** er en slekt av biller som tilhører den artsrike underfamilien Cerambycinae i familien trebukker (Cerambycidae).

## Utseende
Små til middelsstore (7-20 millimeter), slanke og langbeinte, mørke trebukker med tegninger av lyse skjell. Artene kan minne noe om vepser. Antennene er spinkle og kortere enn halve kroppslengden. Pronotum er rundet, litt innsnevret ved roten. Dekkvingene er litt avsmalnende bakover, det bakerste bakkroppsleddet stikker gjerne ut bak dem. Beina er slanke, men ikke påfallende lange.

## Levevis
Larvene utvikler seg i hard og tørr, død ved på greiner og stammer av løvtrær. De voksne billene besøker gjerne blomster.
 
## Utbredelse
Slekten har en nær verdensomspennende utbredelse, men ser ut til å mangle i Sør-Amerika og Australia.
