Bombus soroeensis soroeensis (Fabricius, 1777)

It has been collected in forestal and supraforestal temperate oceanic Pyrenean pastures, in meadows of altitude either with scattered Pinus uncinata , with patches of subalpine scrub, or in peatlands, normally between 1310 and 2600 m ( Fig. 7 ), except in two cases, always above 1700 m, on Achilegia vulgaris L., Acinos alpinum (L.), Campanula glomerata L., Carduus acanthoides L., Cirsium acaule (L.) Scop., Cirsium arvense (L.) Scop., Echium vulgare L. , Epilobium angustifolium L., Gentiana alpina Will. , Gentiana lutea L., Lathyrus pratensis L., Lotus corniculatus L., Onobrichis vicifolia Scop., Phlomis lychnitis L., Rhododendron ferrugineum L., Silene acaulis (L.) Jacq., Trifolium pratense L. , Trifolium repens L. Vaccinium myrtillus L. , Viola odorata L. and Vicia cracca L.

According to the current data, this species exhibits greater elevational tendency ( Fig. 7 ), but it is not regarded as being scarce or threatened ( Table 2 ).
