  • This natural hybrid (Opuntia engelmannii x phaecantha) of two common and local prickly pear cacti - the Engelmann's Prickly Pear (Opuntia engelmannii) and the brown-spined prickly pear (Opuntia phaecantha),  shows characteristics of both and have resulted in a large, mature beautiful cactus growing at some elevation in the Ajo Mountains in Southern Arizona. Since so many of our native members of the Opuntia genus are so closely related and have overlapping natural ranges, hybridization is common among many species, and is the source of much confusion and frustration for biologist and naturalist alike! This particular plant has the beautiful silvery white spines and flower petal shape of O. engelmannii and the flower coloration and growth pattern of O. phaecantha.

    Natural Prickly Pear Hybrid
  • The spiny-fruited prickly pear (Opuntia x spinosibacca) is a naturally occurring hybrid between two overlapping Opuntia species (O. aureispina and O. phaeacantha) found in the Big-Bend Region of Texas and is believed to be reproducing with others of the same hybrid in the wild, which is a common way over time we end up with distinct new species. In some circles, it is already being referred to as a unique species: Opuntia spinosibacca. Although they are considered rare in the wild, I happened to find many hundreds of them in bloom like this one spread out in the lowland region north of the Chisos Mountains in Big Bend National Park in West Texas near the Rio Grande.

    Spiny-Fruited Prickly Pear
  • The brown-spined prickly pear (also regionally known as the tulip or desert prickly pear) is another widespread member of the Opuntia genus that is found throughout all of the American Southwestern States including Nebraska and even South Dakota and is found across most of Northern Mexico. One of the things that make this particular species so amazing is the adaptability to drastically different environments: it can be found thriving in the driest of lowland deserts to the moist, cold forests of the Rocky Mountains. As a result, there are several variable physical attributes that make identifying this species confusing at best. Springtime flowers are variable from lemon yellow, orange or pink, usually with but sometimes without a reddish center. This one was found growing in the Ajo Mountains in Southern Arizona near the Mexican Border.

    Brown-Spined Prickly Pear
  • This great find in a purplish prickly pear cactus flower (Opuntia azurea) in Big Bend National Park in West Texas was an exciting one for me. This bee assassin bug is a clever hunter of bees and other pollinating insects found throughout much of North America. It is most often found inside flowers waiting to stab the unsuspecting insect attracted to the flower's sweet nectar with its sharp proboscis, where it will literally drink its prey dry. Even though this one is covered in pollen, you can still see the warning colors of black and red (aposematic coloration) warning birds and other predators that this bug is not safe to eat or hunt.
