I think these have surprisingly long tongues because they nectar at my firespikes and are the only butterflies to do so (even the zebra longwings, which can reach firebushes, do not).
Love their bright chartreuse color and year-round presence in my area, always a nice photo op when they visit a purple flower.

I have a Christmas cassia now and hopefully will get some cats soon c:

Love the butterfly; the caterpillar, not so much. They love cassia plants.

Caterpillars are either green or yellow. The green version is from eating the leaves of the host plant whereas the yellow larva occurs when the caterpillar consumes the yellow flower buds of the host plant.

In Texas, I have observed the sulphurs nectaring on the abundant wild cedar sage.

This is my favorite butterfly...a bright neon lemon-lime light fluttering in our gardens just brightened my days. We only had one last year...and it stayed til November 4th, just before our hard freeze. This year I'm getting a Cassia 'hebecarpa' plant to make sure we have many more this year!

Huge yellow butterflies that are very common. They can be seen year-around in northern Florida, even coming out on warmer winter days.

Wing span: 2 1/4 - 3 1/8 inches (5.7 - 8 cm).

Identification: Upper surface of male is lemon yellow with no markings. Female is yellow or white; outer edges of both wings with irregular black borders; upper forewing with dark spot in cell. Lower surface of hindwing of both sexes with 2 pink-edged silver spots.

Life history: Males patrol with rapid flight, searching for receptive females. Eggs are laid singly on young leaves or flower buds of host plants; caterpillars eat leaves and rest on underside of leaf petioles.

Flight: Many flights year around in the Deep South; may have one flight in late summer in other southern states; immigrants to northern states in August or September usually do not reproduce.

These guys pretty much stay on my cassia alata, their host plant. They don't do all that much damage and are really lovely butterflies!
