Study on Pemphredon lethifer, an aphid-hunting digger wasp with biocontrol potential: nesting preferences depend on twig pith diameter. Wasps favoured larger diameters (6.5-8.5mm ideal for female offspring). Findings could help design better nest boxes to support this species doi.org/10.3897/jhr....
