We study the singly Cabibbo suppressed decays Λ+c→pη and Λ+c→pπ0 using Λ+c¯Λ−c pairs produced by e+e− collisions at a center-of-mass energy of √s=4.6 GeV. The data sample was collected by the BESIII detector at the BEPCII collider and corresponds to an integrated luminosity of 567 pb−1. We find the first evidence for the decay Λ+c→pη with a statistical significance of 4.2 σ and measure its branching fraction to be B(Λ+c→pη=(1.24± 0.28(stat)±0.10(syst))×10−3. No significant Λ+c→pπ0 signal is observed. We set an upper limit on its branching fraction B(Λ+c→pπ0)<2.7×10−4 at the 90% confidence level
