Grylloblatta campodeiformis

Grylloblatta campodeiformis is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Grylloblatta campodeiformis rather than just read about it. In short: Grylloblatta campodeiformis, also known as the northern rock crawler, is an omnivorous species of insect in family Grylloblattidae. Like other species in the genus Grylloblatta, it is endemic to North America.

Key takeaways

Grylloblatta campodeiformis belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Grylloblatta campodeiformis to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Grylloblatta campodeiformis from memory before moving on to harder problems.

Reference excerpt

Grylloblatta campodeiformis, also known as the northern rock crawler, is an omnivorous species of insect in family Grylloblattidae. Like other species in the genus Grylloblatta, it is endemic to North America.

Taxonomy This species was the first grylloblatid discovered and formally described in the scientific literature by Edmund Walker in 1914. It was originally placed in the order Orthoptera but has since been placed in the order Notoptera. There are currently four subspecies:

Grylloblatta campodeiformis athapaska Kamp, 1979, recorded in British Columbia, Alberta, and Montana Grylloblatta campodeiformis campodeiformis Walker, 1914, recorded in British Columbia Grylloblatta campodeiformis nahanni Kamp, 1979, recorded in British Columbia Grylloblatta campodeiformis occidentalis Silvestri, 1931, recorded in Washington state, US

Description

Adults are typically 3 cm (1.2 in) long, excluding ovipositors and cerci, and are fairly elongate, wingless insects. They are a uniform honey-yellow in colour and covered with very short hair. Unlike some other species of grylloblatid, G. campodeiformis has eyes which have roughly 70 facets. The head is fairly flat and rounded. The thorax is elongate and over a third of the body length. The abdomen is composed of 10 segments and over half the body length. The legs are long and narrow (cursorial) with stout coxae and long femora. Their antennae are long ~9 mm (0.35 in) and thread-like. In adults the number of antennal subsegments is variable ranging from 24 to 27.

Biology Diet Rock crawlers are nocturnal predators and scavengers that actively search for small, invertebrate prey. They also venture onto snowfields, foraging for “insect-fallout” carried and deposited there by wind.

Distribution and habitat This species was originally discovered on Sulphur Mountain, Alberta in the Canadian Rockies at an altitude of 6,500 feet (2,000 m). Subsequently it has been recorded from British Columbia (Canada), Montana, Washington (USA). They are ground dwelling animals, living between small stones and debris during the day. While they can survive warmer temperatures of up to 20.5 °C (68.9 °F) they are typically nocturnal, becoming active on snow fields at cooler temperatures of around 0 °C (32 °F) making them psychrophilic. Like other North American grylloblattids, G. campodeiformis is at some risk of extinction due to its habitat requirements and reduced mobility.

Worked examples

Example 1 — a first encounter with Grylloblatta campodeiformis

Start with the simplest possible case. Write down what Grylloblatta campodeiformis claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Grylloblatta campodeiformis before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Grylloblatta campodeiformis ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Grylloblatta campodeiformis

In research: Grylloblatta campodeiformis appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Grylloblatta campodeiformis in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Grylloblatta campodeiformis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Grylloblattidae, Insects of Canada, Insects of the United States, so understanding it makes those chapters shorter.
In everyday life: Look for Grylloblatta campodeiformis outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
