The caterpillars eat their match, part two

When they eat the leaves of their host plants, the caterpillars of the orange-barred sulphur butterfly are green.  However, the one that I found was not eating the leaves, nor was it green.

An orange-barred sulphur (Phoebis philea) caterpillar on a Christmas cassia (Senna bicapsularis) flower.  The flower to the right had already been reduced to almost nothing, presumably by the same caterpillar.

Instead, the caterpillar was the same bright yellow as the flower on which it rested -- and which it would soon eat.  The only thing that prevented the caterpillar from blending in with the flower completely was its pattern of black stripes and spikes.

A few minutes later, the flower's style had already been consumed by the caterpillar.
