Source-derived summary

Tropidacris collaris, the blue-winged grasshopper or violet-winged grasshopper, is a large South American species of grasshopper in the family Romaleidae. As suggested by its name, in flight the wings are usually conspicuously blue, but they can occasionally be grayish or greenish. Adult males are typically 5–7 cm (2.0–2.8 in) long and females typically 8.5–10.5 cm (3.3–4.1 in) long; the wingspan is usually about 18 cm (7 in). The gregarious and flightless nymphs are aposematically colored in black, red and yellow and are presumed to be toxic; a researcher who tasted one noted, that it was very bitter, similar to a monarch butterfly.

Tropidacris collaris is common in a wide range of habitats from rainforests to dry open areas like Caatinga and Cerrado. It is widespread in South America east of the Andes, from Colombia and the Guianas to central Argentina, but generally avoiding highlands. They feed on many types of plants, including several species of agricultural crops, trees grown in plantations and ornamental plants, and they are considered a pest in some parts of their range. They are popular among insect and terrarium enthusiasts.

A grasshopper of this species was spotted landing on the arm of James Rodríguez, after he scored a goal during Colombia's 1–2 loss to Brazil, at the quarter-finals of the 2014 FIFA World Cup.

Editorial summary

The public source identifies “Tropidacris collaris” as species of insect. This brief keeps that definition visible, then builds a research path around Tropidacris, collaris and species.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current lead gives the account dated anchors—2014—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Tropidacris, collaris and species providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Tropidacris collaris”, the useful work is to connect “species of insect” to the records capable of establishing context and consequence.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Oct 2, 2025. The linked authority identifier is Q10704980. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2014.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
