'''''Trypoxylon''''' is a genus of wasps in the family Crabronidae. All ''Trypoxylon'' species that have been studied so far are active hunters of spiders, which they paralyse with a venomous sting, to provide as food to their developing larvae.<ref>{{Cite journal|last=Camillo|first=Evandro|last2=Brescovit|first2=Antonio D.|date=June 1999|title=Aspectos biológicos de Trypoxylon (Trypargilum) lactitarse Saussure e Trypoxylon (Trypargilum) rogenhoferi Kohl (Hymenoptera: Sphecidae) em ninhos-armadilhas, com especial referência a suas presas|journal=Anais da Sociedade Entomológica do Brasil|volume=28|issue=2|pages=251–265|doi=10.1590/S0301-80591999000200008|issn=0301-8059|doi-access=free}}</ref><ref>{{Cite journal|last=Fox|first=Eduardo Gonçalves Paterson|last2=Solis|first2=Daniel Russ|last3=Rossi|first3=Mônica Lanzoni|last4=Feitosa|first4=Rodrigo Machado|last5=Brescovit|first5=Antonio Domingos|date=2012-03-30|title=The larval morphology and nest habits of Trypoxylon (Trypargilum) rogenhoferi Kohl 1884 (Insecta: Hymenoptera: Crabronidae)|journal=Zootaxa|volume=3251|issue=1|pages=47|doi=10.11646/zootaxa.3251.1.3|issn=1175-5334|hdl=11449/733|hdl-access=free}}</ref> Depending on the species, they will either construct their own nest from mud or find cavities that already exist.<ref>[https://jhr.pensoft.net/article/9997/element/7/0/crabronidae/ Journal of Hymenoptera Research]</ref> These cavities can range from keyholes to nail holes to previously abandoned nests, and are generally sealed with mud to create cells for their larvae. {{Citation needed|date=December 2018}}
==Worldwide distribution== The 634 species in this most speciose genus are found worldwide being represented in the Palearctic, Nearctic, Afrotropic (largest number of species in the Old World), Neotropic (highest number of species), Australasia (poorly represented) and Indomalayan realm. <ref>[http://researcharchive.calacademy.org/research/entomology/entomology_resources/Hymenoptera/sphecidae/Genera/Trypoxylon.pdf California Academy of Sciences Institute of Biodiversity pdf]</ref>
