If it happened overnight it's probably a noctuid moth caterpillar.
The big problem with them is they are very mobile caterpillars so you never know if they have stuck around or have moved on. BTK (Bacillum thuringiensis var. kurstaki) is effective and harmless to pollinators but some noctuid caterpillars and armyworms are immune to it, so weight your options carefully.
Thus, from the war of nature, from famine and death, the most exalted object which we are capable of conceiving, namely, the production of the higher animals, directly follows. There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.
-Charles Darwin-
