Caespitosus = spines growing in clusters or tufts

Echinocereus reichenbachii subsp. caespitosus - Texas Lace Cactus can come in many spine colors and have quite a lot of variation in flower colors and sizes.  I would say the cactus above is subspecies 'caespitosus' from Central Texas given the extra large flower and the relatively increased projection of spines in contrast to the more typical reichenbachii (below) where the spines are tightly held and can easily be touched without the fear of retribution.

Texas vervain - Verbena halei

Two-tailed Swallowtail

Papilio multicaudata - Two-tailed Swallowtail - Many of the older maps have this species occurring in a range starting about 150 miles West of Austin.  However, newer maps have shifted this direction either by correction or expansion of its native range.  I find them frequently in Austin in close proximity to Escarpment black cherry trees.
