%X The blazars B2 1811+31 and GB6 J1058+2817 were found to be in flaring state during 2020 and 2021, respectively. The high states of the sources were registered by the Fermi-LAT at energiesbelow 100 GeV, triggering observations at higher energies with the MAGIC telescopes, in theUV/X rays with the Swift satellite and with ground-based radio and optical telescopes. Theobservations in the very-high-energy (VHE, 100 GeV < E < 100 TeV) gamma-ray band led tothe first detection of both sources in this energy range. A long-term gamma-ray lightcurve wasderived using Fermi-LAT data, identifying the time intervals in which the two sources persistedin a quiet state. Archival data collected in the radio to X-ray wavelengths showed that the twosources exhibited intermediate-synchrotron-peaked BL Lac behaviors in their low states, ratherrare sources in the TeV sky. The high state of the two sources was deeply investigated thanks to thecoverage provided by multi-wavelength (MWL) observational campaigns. In this contribution,we present the results of the gamma-ray observations which are included in a MWL observationalcampaign organized on these sources during their high-states. We discuss the flare spectralproperties and temporal variability. In the high-energy gamma band, sub-daily-scale variabilityand strong spectral hardening give evidence for compact emission regions responsible for theradiative output at high energies during the flare.
