Trip to a Butterfly and Bug Zoo
When we got to the GT Butterfly House & Bug Zoo, Jules, who has been an animal professional for 10 years,
welcomed our class and told us a lot of information about different types of
giant beetles. Jules showed us a beetle which they fittingly named Dwayne “The
Rock”. This beetle is a Hercules beetle (Dynastes
hercules) and this species can be found in Central America. The
males have large horns used for competing with other males to win over a female.
Their pupae phase lasts for a month and after that, they live for about 3-6
months. Their diet as larvae consists of rotting wood and as adults, they eat
fruit. At the zoo, they use beetle jelly to feed the beetles, which actually
comes from Japan where beetle wrestling is apparently a popular event. A fun
fact that Jules shared about the Hercules beetle is that the elytra change
colors when there are changes in humidity. We also got to see a giant stag beetle (Lucanus elaphus) named Sparky B which originates from Asia and
has very large mandibles, also for fighting other males. Something that Jules
emphasized is that they like to name the insects so that when they show them to
people, they will be able to see them as more than just scary insects.
The butterflies in the garden were shipped from Costa Rica, so
they are not native species that would be found in Michigan. Everything at the
butterfly garden is heavily regulated to make sure none get out because they
could end up being invasive or carry parasites. We were told by the staff that
there were 45 different species in the garden. Some of them were still in their
chrysalis or cocoon, and we didn’t get to see any coming out of their pupa
stage but there were plenty of butterflies to see flying all around the garden.
There was also an atlas moth (Attacus atlas), which is one of the biggest lepidopteran
species, but it only lives as an adult for 5-7 days. Some of the other species
that were spotted were the Giant Owl (Caligo memnon), Blue Morpho (Morpho
peleides), Green Clipper (Parthenos sylvia), and Doris Longwing (Heliconius
doris). Most of these butterflies only live for a couple of weeks, but the
staff continues to care for the butterflies and moths until they pass
away.
The trip to the butterfly and bug zoo was a nice way to wrap up the last full day of class… and so was the ice cream afterward! Shout out to Dr. Hoekman for the ice cream/slushies! We got to learn so much about the different insects and other animals they had at the zoo, and even got a chance to hold some of the insects and see them up close. After taking Insect Ecology, I have gained a lot more respect for insects. I’ve also realized how complex they are for being so incredibly small and I’ve learned so much about their vital role in ecosystems.
