CENTRAL FLORIDA CRITTER OF THE DAY: Coffee-loving Pyrausta Moth Caterpillar (Pyrausta tyralis)

I can officially confirm that this is P. tyralis.  How do I know?  I reared one that was a little older in a container.  Best part is that it was reared using the plant I found it on which was BIDENS ALBA!!!!!!!!!

Small diurnal moth (flies during the day)

CENTRAL FLORIDA CRITTER OF THE DAY: Green Lacewing Debris-Carrying Larvae (Family Chrysopidae)

Shown on Florida Native Plant: Bidens alba

It must be lacewing week at my place.  Found lots of larvae cleaning up the stems and leaves and flowers of various plants including Bidens alba, Dogfennel and Fleabane and grasses.

larval and adults are beneficial predators of other insects, especially aphids.

You can really see the pinchers in this photo on a grass

looks like a tiny bird dropping on a fleabane leaf

This one on Dogfennel was munching on ants. they cover themselves with the carcasses of the insects they eat.

In my yard that would be the Baccharis Halimifolia aka Groundselbush or Saltbush.

CENTRAL FLORIDA CRITTER OF THE DAY: White Checkered-Skipper Butterfly Caterpillar (Pyrgus albescens)

I’d been watching this caterpillar for a few days.  They roll in leaves during the day and I was surprised to find it rolled in a Bidens alba leaf.  It had nipped off a bud from its larval host and then secreted itself making its tent out of the bidens which was growing within the Sida.
