  Let $(F_n)_{n \geq 1}$ be the sequence of Fibonacci numbers. For all integers
$a$ and $b \geq 1$ with $\gcd(a, b) = 1$, let $[a^{-1} \!\bmod b]$ be the
multiplicative inverse of $a$ modulo $b$, which we pick in the usual set of
representatives $\{0, 1, \dots, b-1\}$. Put also $[a^{-1} \!\bmod b] := \infty$
when $\gcd(a, b) > 1$. We determine all positive integers $m$ and $n$ such that
$[F_m^{-1} \bmod F_n]$ is a Fibonacci number. This extends a previous result of
Prempreesuk, Noppakaew, and Pongsriiam, who considered the special case $m \in
\{3, n - 3, n - 2, n - 1\}$ and $n \geq 7$. Let $(L_n)_{n \geq 1}$ be the
sequence of Lucas numbers. We also determine all positive integers $m$ and $n$
such that $[L_m^{-1} \bmod L_n]$ is a Lucas number.
