Lucanus elephus
Elephant Stag
Definitely the most impressive of the 27 U.S. stag species. This monster can measure nearly three inches (70 mm) including the mandibles. Females, however are small and unimpressive and use their short jaws to carve out rotten wood which they compact over their eggs. Rearing info on L. elephus. |
Dynastes granti
Grant's Rhinoceros Beetle
This is the largest US rhino with large wild caught specimens coming in at 65-75mm and a record specimen at 85 mm. However, many wild males are small, only around 35-45 mm. If the larvae are fed a variety of foods including rotten hardwood, composted manure, and rotten leaves (plus the occasional piece of dry dog food), adult males raised are always over 60 mm.

Dynastes tityus
Eastern Hercules Beetle
The color of this beautiful monster can range from army green to bright yellow. Like D. granti the adults love watered-down, real maple syrup, but will also accept pear, grape, apple, watermelon, etc. If properly reared, adults rival D. granti in size but not length due to the different horn structure. The male pictured is an exceptional, captive-bred specimen. Rearing info on D. tityus. |
Zylorictes thestalus
This small rhino looks similar to the different foreign Oryctes species and is kept similar to Dynastes. Though Zylorictes can be very common in the wild captive breeding is extremely difficult. |
Megasoma punctulatus
Megasoma punctulatus is the second rarest of the three U.S. species of Megasoma. The adult is a very handsome beetle which is not too difficult to rear. From egg to adult takes two years, three under poor conditions. Unfortunately it is extremely difficult to find living M. punctulatus females. Their homes are being used for land development and captive breeding may be the only hope for a future. Rearing info on M. punctulatus. |
Strategus anteus Ox
Beetle
S. anteus are native to most of the U.S. but are usually uncommon. However in some areas in Florida large colonies covering a few blocks are found. The larvae feed on rotten leaves and roots. The feeding does little damage but the adults love to dig up the grass which makes for an ugly lawn. Rearing info on S. anteus. |
Cotinis texana Fig
Beetle
Fig beetles are one of the few day active large beetles. They are such spectacular fliers and possess a 2+inches (50 mm+) wingspan. Adults eat soft fruits while larvae are kept well on compost manure, rotten wood, and cracked corn (unable to chew whole kernels). Despite popular belief larvae starve to death if fed plant or tree roots. Rearing info on C. texana. |
Osmoderma eremicola
Hermit Beetle
Hermits are robust medium-sized scarabs with very strange sculpturing on the pronotum which varies much by size and individual. Rearing is the same as for Dynastes. In the wild hermits life-cycle is two years but after a few generations captive breeding the time from egg to adult is only 6-7 months. Rearing info on O. eremicola. |
Plusiotis beyeriBeyer's Jewel Scarab
Similar rearing to P. gloriosa but adults also feed on oak leaves. Ova take over a month to hatch and the larvae like the beetles are twice the size of P. gloriosa. P. beyeri is the neatest of all U.S. flower beetles with its larger size, satiny green body, and bright purple legs. This species also usually becomes an adult in less than 1 year from ova being laid. Rearing info on P. beyeri. |
Moneilema armata
Cactus Beetle
Cactus beetles are strange looking longhorn beetles that only feed on a few species of cactus. Adults feed from the outside and larvae feed from within. Adults live as much as a year but more often only four to six months. Rearing info on M. armata. |
Megaphasma dentricus
This is the largest of the U.S. Phasmids with the females often growing to (150 mm) 6 inches! Males have enlarged middle and back legs with a spine near the apex of the femur which they use to stab rival males. Males are beautiful with a glossy forest green stripe down the back, numerous tan markings, and red-brown under the femurs and on the head. Females are not usually as colorful and may be gray and green or purple gray. In captivity the species happily accepts any type of willow. Rearing info on M. dentricus. |
Anisomorpha ferruginea
Western
Two-stripe
Anyone who thinks that stick insects are defenseless creatures will be quite sorry if they play with one of these. These striped sticks shoot out an incredibly noxious fluid up to a few feet. The liquid is said to cause temporary blindness but is harmless if washed out thoroughly. The fumes from the liquid make eyes water and cause sneezing. Rearing info on A. ferrunginea. |
Diapheromera femorata
Northern Walking Stick
This is by far the most common US walkingstick and most anyone who has seen a stick-insect as child saw this species. Although very small and delicate looking, this is a pretty tough little critter and will feed on the leaves of rose, apple, viburnum, raspberry, etc. This stick is often misidentified by overzealous hobbyists as M. dentricus which is not very odd because the appearance is similar. Eggs of D. femorata are shiny and M. dentricus ova are dull and about 10 times the mass. Female photo. |
Abedus herberti Giant
Waterbug, Toe-biter
The adults of this species measure in at 40mm and unlike the larger Lethocerus sp. are easy to rear. Females simply lay a mat of eggs on the males back and he diligently cares for the eggs which hatch about 18 days later (at 75F). These giant water bugs have a lot of personality and speed and are fun to watch as they catch their prey whether it is a tadpole, snail, cricket, salamander, or something bigger. Rearing info on Abedus herberti. |
Thasus acutangulus Giant
Mesquite Bug
Measuring often over 50mm, this is the most impressive US Hemipteran. Yellow-veined brown hemelytra, red disks in the middle of each antennae, spines off the sides of the abdomen, red markings on the legs, and enlarged and spined back legs on the male make this a formidable creature. Surprisingly, this wicked looking animal is content to suck sap from mesquite plants and five or six adults can feed from tiny plants (less than 6 inches- 150mm) without appearing to cause any damage.

Romalea microptera Southeastern
Lubber
A very beautiful creature which is usually covered in shiny black armor and yellow spots and stripes. Adults will eat carrots, many types of leaves, dog food, seeds, and probably many other things. Ventilation (screen type lid) is very important or nymphs and adults "mysteriously" die. Egg pods should be kept slightly cool for a few months or the eggs may take forever to hatch. Rearing info on R. microptera. |
Samia cynthia Cynthia
moth
The Cynthia moth has only been "native" to the US since the 1800's when it was introduced from China as a possible alternative to the domesticated silk moth. S. cynthia is usually only found where the Tree of Heaven (Ailanthus) is growing. Caterpillars will also feed on staghorn sumac, willow, and others but will not grow as big or as quickly. Adults do not feed and seldom live over seven days. Rearing info on S. cynthia. |
