Late Departure

It's 81 degrees F (with a low of 63 degrees F) and the humidity is 69%. That's hot and humid for December. We had a 33 degree day in October! Crazy weather.

This hot and humid weather has been hanging around for over a week. The Gulf Fritillary butterflies are still around, but I'm only seeing 3 at the most on a given day. The native passionvine vines are all brown and dead. There are new shoots coming up from the roots. Those shoots are sustaining the few caterpillars that are still around. The tropical salvia and lantana are feeding the adults, aided by the dandelion that has decided to begin popping up.

The non-native passionvine that is planted in the Jasper Arboretum (we think it's the "Incense" hybrid), still has several green leaves and a couple flowers, and the Gulf Fritillarys seem to hang around it, but there is not much damage from caterpillars. They are not eating it despite the lack of a native food source. This makes me think that these butterflies may not be adapted to eat this non-native species. That happens with many exotic plants - they are resistant to pests simply because they didn't evolve with the insects in the area.

I do not think Gulf Fritillarys migrate. I need to do more research on this subject.

I did do a lot of research on Passiflora incarnata (the native passionvine) and gave a powerpoint presentation to the Master Naturalists, which was was received. It's amazing how many species are in the world (485-ish and even more if you count all the hybrids)! It may be worthwhile to become an expert on our particular native species.
