A butterfly has 2 pairs of wings, 3 pairs of legs, and 1 pair of antennas. There are 130 butterflies. How many less antennas than wings and legs combined?
The number of wings is 2 pairs * 2 wings/pair = <<2*2=4>>4 wings.
The number of legs is 3 pairs * 2 legs/pair = <<3*2=6>>6 legs.
So, the number of wings and legs combined is 4 wings + 6 legs = <<4+6=10>>10.
Thus, there are 10 - 1 pair = <<10-1=9>>9 less antennas than wings and legs combined. Answer: \boxed{9}.
