Meet Insectarium Keeper Mandy Pritchard

Contributors: April Pitman, Wendy Rice, and Jenna Wingate

Mandy Pritchard works as a keeper at World of the Insect, also called the Insectarium. Mandy has a solid entomology background and she is very knowledgeable of the biology and taxonomy of a variety of different species of insects. As a keeper, Mandy is in charge of maintaining and breeding 15 species. Most of her species require fresh plant cuttings, so you will see her out in the park every day (rain, shine or snow) looking for the best plants for her cultures.

According to her colleagues, Mandy is an awesome coworker. She helps train volunteers and new hires, and whenever her coworkers go to her with questions, she is always open and willing to help. Mandy is very easy to get along with and is one of the reasons the Insectarium is such a team-oriented and cohesive department.

Additionally, Mandy is an awesome representation of the zookeeping profession because of her passion for conservation. She goes above and beyond her job as a keeper. Currently, she is in charge of the American Burying Beetle reintroduction program at the Zoo. She successfully collaborates with other agencies outside the Zoo (Ohio Fish and Wildlife, Fernald Preserve, and more) to work towards a lasting conservation solution. The program itself is requires much diligence and hard work. Mandy is in charge of organizing dates for the release, helping to staff the release, raising the beetles, setting traps to survey the area before and after the release, and much more.

One of the most important things keepers do is educate the public on conservation and Mandy does a great job of that. Sharing her passion with the public comes naturally to Mandy. She just recently gave a talk at the Fernald Preserve (where the beetles are released) to help educate the public on the importance of this species. It is not the easiest thing to show people why this beetle should be saved. Most people just see it as another bug! But Mandy does a great job of enlightening everyone, keeping the audience interested and even getting a few laughs, too! Mandy has the ability to make people care about something they never thought they would. Keep it up, Mandy!

American Burying Beetle Release – Round Two

On July 1st, 2014 the Cincinnati Zoo & Botanical Garden released over 100 critically-endangered American Burying Beetles (ABB for short) at the Fernald Nature Preserve. This was the second of at least five years of releases planned at the preserve. As you might have read in previous blog posts I have been working closely with Fernald and the USFWS for the past four years to ensure that this species has an opportunity to make a comeback. This six-legged beauty has a very bazaar yet important role as a decomposer. Pairs of ABBs raise their young on the carcasses of small mammals and birds that they literally bury. While this might sound gross, these beetles and other decomposers are vital to the health of the ecosystem. Animals like these act like nature’s garbage men, removing and re-using things that no one else wants to deal with.

When the beetles were released last week they were provided with rat carcasses and methodically placed in the ground to breed. The release sites were carefully marked and protected from scavengers with layers of fencing. Next week we will return to check on the success of this year’s release by digging up about 20% of the carcasses. We will count any larvae and place them back in the soil to finish out their life cycle which will take about two more months.

This fall I will perform a post-release survey to check for any new adult ABBs at the preserve. The survey consists of setting and baiting pit-fall traps around the preserve that attract and trap live ABBs and other related beetles. So what exactly do you bait these traps with? I’m glad you asked! Inside each of these traps we place a container of steamy, foamy, week old, rotten chicken!



I assumed this aspect of the job would be pretty unpleasant when I signed up for it, but WOW did I underestimate the lingering, ghastly stench of rotten poultry. It works like a charm though. Within minutes these traps attract all sorts of carrion beetles. If ABBs are in the area, this level of stink will certainly attract them.

ABBs are capable of flying over two miles a night, and Fernald is roughly one square mile. Our survey efforts are limited to the preserve; therefore it can be hard to gauge the overall success of these reintroductions. While we have not yet recaptured any ABBs at Fernald, other reintroductions in the US have yielded positive results, so we remain hopeful. I truly believe that efforts by the Cincinnati Zoo & Botanical Garden and other involved institutions will have a positive impact on this species’ general population status.

Thanks to everyone involved with this year’s American Burying Beetle release!

A Tale of Two Mantises

Praying Mantises, insects in the order Mantodea were so named because of the prayer-like posture of their folded front legs. In the eyes of their prey there’s nothing divine about mantises. There are more than 2,300 species of mantises worldwide and while they vary in size, shape and color they all have one thing in common, they are voracious predators. Cincinnatians can encounter two remarkable mantis species; the native Carolina Mantis (Stagmomantis carolina) and the introduced Chinese Mantis (Tenodera sinesis).

The Carolina Mantis varies in color from light-green to medium-gray and is normally between 1-1/2″ and 2-1/2″ long. These mantises range from the eastern and central United States south through Central America and into northern South America. Carolina Mantis nymphs have the ability to alter their color to match their habitat each time they molt. Adult male Carolina Mantises are strong fliers and will actively stalk their prey. Adult female Carolina Mantises have shortened wings and are heavier bodied; they cannot fly so they lie in wait to ambush their prey.

The Chinese Mantis varies in color from light-green to brown and is normally between 3-1/4″ and 4-1/4″ long. Native to Eastern Asia the Chinese Mantis was allegedly introduced to the United States late in the 19th century to control agricultural pests. By most accounts the Chinese Mantis has done little to control pests despite having become established throughout most of the United States. In some areas the presence of the larger Chinese Mantis has negatively impacted the smaller Carolina Mantis.

Both Carolina and Chinese mantis hatchlings emerge from egg cases in spring and are so small they can be dispersed by strong winds. As the young mantises grow so too does their choice of prey; tiny fruit flies are replaced by increasingly larger flies, bees and moths. Adult Carolina Mantises can capture medium-sized butterflies while adult Chinese Mantises can capture hummingbirds. Both species will mate in late summer or early autumn, leaving their egg cases on the stems of shrubs or bushes. These egg cases will endure even the harshest winters to deliver the next generation the following spring.

Mantises are among the world’s most recognizable and beloved insects. Their grace and ferocity have inspired poets and martial artists. Children the world over have marveled at them in backyards and kept them as pets in quart jars. If you see a mantis this summer please take a few minutes to observe and appreciate one of Cincinnati’s most amazing insects.
