Biology and notes. Some indivudals of T. calceolatus  recently captured showed some grade of melanism in the tergites, with yellow fasciae thinnest, which can due to coldest conditions of growing habitat of larvae. Toxomerus calceolatus  is associated with the native herbaceous and tree species Anagallis alternifolia Cav.  var. and  E. cordifolia  , respectively ( Smith-Ramírez et al. 2005, 2016). This flower fly species has been observed visiting B. rapa  (Joaquín López, CSP record); Baccharis  sp. (Matías Cortés, CSP record); Hebe speciosa (A. Cunn) J. C. Andersen  (Fernanda Gatalina, CSP record); T. officinale  (Daniel Cross, Gabriel Germain and Victor Jesam, CSP records); Ranunculus  sp. (Norka Contreras, CSP records) and R. raphanistrum  (Ani Mari and Felipe Cabello, CSP records).

Conservation status. LC; EOO = 516,491 km 2, AOO = 56 km 2 and 15 localities (or subpopulations).
