The Eagalante

Devin adjusted a tiny spring and set the trap back down. It blended in with the forest floor so well that after he blinked he couldn't see it. He squinted, turning his head slightly this way and that, and finally picked it out again against the leaves. He pushed a red golf-tee into the earth by his foot so that he'd know where to kneel and look for it again if it didn't catch anything, and then stood up and near-silently walked away.
The woods were quiet, which meant that there was some bird-song in the canopy overhead, and the occasional rustle of a rabbit or other small game in the bushes. Devin ignored them, as game went they were all too large. He trapped only the smallest of small game: exotic mice, teacup cats, rare cockroaches, and now, the Eagalante. He hoped.
He'd overheard two men talking in low voices about the Eagalante in the pub. He been drinking by himself, sat at a small round table covered in pint glasses, thinking (again) about writing a book about his career and wondering how long it took to learn to write. They'd been quiet, but they were sat at the next table, and when one man had leaned in, and the other had followed suit, Devin had been intrigued. And listening for very quiet noises and tiny movements was absolutely necessary as a hunter of very small game.
The Eagalante, said the first man, had been seen in the woods again. His wife had been out picking mushrooms when she'd been knocked over; when she stood up, she'd not been able to see anything. Then she was knocked over again, and she heard the rushing of tiny feet through leaves. When she looked round, she saw a pair of horns disappearing into the ground. He'd gone back later, he said, and looked around, and he'd found the tracks. The giant horned ant, the size of a rat, the Eagalante, was back in the woods at last.
At last? asked the second man. The first had nodded, but had been stopped from saying anything by the arrival of two bedraggled women, presumably their wives, who announced, unnecessarily, that it was raining outside.
Devin had read up a little, and discovered that the Eagalante was called a giant horned ant, but that the horns were more like antlers, and that it could spit a white frothy, poisonous mass from its mandibles when upset. There were sketches of it, and it looked entirely trappable. Devin decided that it would be his next target, and started building traps so small yet powerful that standing on them entailed a trip to the hospital to get them removed and get a fresh tetanus injection.
As he approached the next trap spot, he heard a grunting sound, like a miniature rhinoceros, and he slowed his pace. Had he trapped the Eagalante?
