BUYS, Sandor Christiano. Last instar larva of Trypoxylon (Trypoxylon) maidli Richards (Hymenoptera, Crabronidae), with biological notes on one nest. Rev. Bras. Zool. [online]. 2003, vol.20, n.3, pp. 447-449. ISSN 0101-8175.  http://dx.doi.org/10.1590/S0101-81752003000300013.

The last larval instar and the cocoon of Trypoxylon (Trypoxylon) maidli Richards, 1934 are described. This larva is apparently indistinguishable from that of T. clavicerum exiguum Tsuneki, 1956. They can be distinguished from larvae of other species in the subgenus by the following features: integument of body smooth, sensilla on both sensorial area and labrum, and distinct parietal bands. Notes on nesting site and preys from one nest are presented. Eurycoma insigne (Millidge, 1991) (Linyphiidae) and Argiope argentata (Fabricius, 1775) (Araneidae) are reported as preys.
